===== Kidney stones MUST ULTRASOUND ====
Saturation levels of uric acid in blood may result in one form of kidney stones when the urate crystallizes in the kidney. These uric acid stones are radiolucent and so do not appear on an abdominal plain x-ray or CT scan. Their presence must be diagnosed by ultrasound for this reason. Very large stones may be detected on x-ray by their displacement of the surrounding kidney tissues.

A few years ago:
I remember that the ultrasound did show a big stone,
a later x-ray showed nothing much.
I did drink a lot and passed the stone (it was very painful!)

I remember feeling terrible after eating lots of lentils.

Uric acid crystals can also promote the formation of calcium oxalate stones, acting as "seed crystals" (heterogenous nucleation)

Nine patients (five with normal renal function, one after liver-kidney transplantation, and three with renal failure) completed the IxOC-2 study. Seven patients (six with normal renal function and one after liver-kidney transplantation) completed the IxOC-3 study. Urinary oxalate or plasma oxalate in renal failure was determined at baseline, weekly during treatment and for a 2-week follow-up. The patients who showed >20% reduction both at the end of weeks 3 and 4 were considered as responders. Under IxOC-2, three out of five patients with normal renal function showed a 22-48% reduction of urinary oxalate. In addition, two renal failure patients experienced a significant reduction in plasma oxalate and amelioration of clinical symptoms. Under IxOC-3 treatment, four out of six patients with normal renal function responded with a reduction of urinary oxalate ranging from 38.5 to 92%. Although all subjects under IxOC-2 and 4 patients under IxOC-3 showed detectable levels of O. formigenes in stool during treatment, fecal recovery dropped directly at follow up, indicating only transient gastrointestinal-tract colonization. The preliminary data indicate that O. formigenes is safe, leads to a significant reduction of either urinary or plasma oxalate, and is a potential new treatment option for primary hyperoxaluria.

Energiereicher Blitz in der suedlichen Hemisphaere

Der grellste Blitz aller Zeiten

Astronomen haben im Sternbild Carina einen Gammastrahlenausbruch entdeckt, der alles bisher Dagewesene übertrifft. Berechnungen zufolge sind die Strahlen 12,2 Milliarden Jahre durch den Kosmos gerast, bis sie die Erde trafen.

Ausbruch der Superlative


In Energiemengen gemessen sind Gammastrahlenausbrüche die Schwergewichte der an bizarren Erscheinungen nicht gerade armen kosmischen Welt. Aber jener Blitz, der in der Nacht vom 15. auf den 16. September die Zeiger der Messinstrumente ausschlagen ließ, stößt offenbar in neue Bereiche vor: Wie Forscher im Fachblatt "Science" (online) berichten, waren die auf der Erde registrierten Gammastrahlen 3.000 bis fünf Milliarden Mal energiereicher als sichtbares Licht.

"Strahlenausbrüche in dieser Größenordnung sind nicht wirklich gut verstanden", sagt Peter Michelson von der Stamford University. Er ist der Chefwissenschaftler am Fermi Gamma-Ray Space Telescope (FGST), mit dem der Lichtblitz zuerst registriert wurde.

Licht vom Ende des Universums

Ein Team um den deutschen Astronomen Jochen Greiner fand später heraus, dass der Blitz am Südsternhimmel nicht nur sehr intensiv, sondern auch sehr alt ist. 12,2 Milliarden Lichtjahre haben die energiereichen Photonen bis zur Erde zurückgelegt, zeigen Messungen mit einem Teleskop der Europäischen Südsternwarte in La Silla, Chile.

Viel weiter weg bzw. älter geht es nicht: Astronomen gehen derzeit davon aus, das der Urknall vor rund 13 Milliarden Jahren stattgefunden hat. "Das war schon vorher ein faszinierender Strahlenausbruch", sagt Julie Mc Enry, die ebenfalls am FGST arbeitet. "Aber mit dieser Distanz kann man ihn nur mehr 'außergewöhnlich' nennen."

Mit Hilfe der Entfernung ermittelten die Forscher auch die Größenordnung der gigantischen Explosion im Sternbild Carina. Sie setzte offenbar Energien von 9.000 handelsüblichen Supernovae frei, Teilchen wurden daraufhin auf 99,9999 Prozent der Lichtgeschwindigkeit beschleunigt - bis dato die extremsten Werte seit es astronomische Beobachtungen gibt.

Rätselhafte Zeitverschiebung


Abseits der Superlative gibt der Strahlenausbruch mit dem Namen "GRB 080916C" auch einige Rätsel auf. Besonders auffallend ist etwa die Tatsache, dass es zwischen energiereichen und energieärmeren Signalen offenbar einen Zeitabstand gibt. Im Prinzip gibt es für diesen Verzögerungseffekt zwei Erklärungen: Die eine macht die durchaus komplizierte Umgebung von Gammastrahlenausbruches dafür verantwortlich.

Sie sind in der Regel von Resten der Sternenexplosion, einem Magnetfeld, einem Schwarzen Loch, beschleunigten Partikeln sowie einer Unmenge von Strahlung umgeben. Peter Michelson vermutet, dass die Strahlen unterschiedlicher Energie "entweder an verschiedenen Orten dieser Region gebildet wurden oder sogar durch einen ganz anderen physikalischen Mechanismus."

Die Quantenschaumtheorie


Spekulativer, aber auch aufregender ist indes eine Erklärung, die sich auf die Theorie der Quantengravitation beruft. Formal gelungen ist die Vereinigung von Gravitations- und Quantenphysik zwar noch nicht, aber es gibt zumindest einige grundlegende Aussagen, die mit diesem Konzept verbunden sind.

Demzufolge sollte der Raum auf der Skala kleinster Abstände nicht glatt, sondern vielmehr "gekörnt" und turbulent, gewissermaßen ein "kochender Quantenschaum" sein. Theoretiker haben berechnet, dass energiearme Gammastrahlen etwas schneller durch diesen Quantenschaum reisen würden als solche mit hohem Energiegehalt.

Der Unterschied wäre zwar extrem gering, aber während einer 12,2 Milliarden Jahre dauernden Reise könnte er sich durchaus so weit aufsummieren, dass man ihn auch messen könnte. Wenn diese Theorie stimmt, dann müsste die zeitliche Verschiebung vom Abstand des Gammablitzes abhängig sein.

Das wäre eine testbare Prognose - allerdings mit einer Voraussetzung: Es müssten zu Vergleichszwecken noch mehr Blitze dieser Art die Erde treffen. "Dieser extreme Strahlenausbruch wirft jede Menge Fragen auf", sagt Michelson . "In ein paar Jahren haben wir vielleicht schon ein gutes Sample solcher Ausbrüche. Und vielleicht haben wir auch ein paar Antworten."

SAT CRASH - Satellitenzusammenstoß - Weltraumschrott

At 16:56 UTC on February 10, 2009; a collision occurred between Iridium 33 and Kosmos 2251, a defunct Russian military communications satellite. Iridium plans to move one of its in-orbit spares into the network to replace the destroyed satellite within 30 days of the collision. This is the first time two intact satellites have collided. Iridium 33 was in active service when the accident took place but was one of the oldest satellites in the constellation, having been launched in 1997.

KOSMOS 2251

Conspiracy? Deliberate smash?

HIGHLY Unlikely.
- Russians had no control over their satellite for many years
- If they had, they would have used a more valuable target. Iridium Satellites provide slow-modem speed (28k8 kbit/sec), mostly to support civilian telephony (artic stations) and NGO and disaster relief. The US military doesn't depend on the obsolete technology.
- There are many dozens of iridium satellites. Killing one of them makes not even a dent in the communication service that (the bankrupt) IRIDIUM system provides.

On 10 February 2009 at 16:56:00 UTC, Iridium 33 (97-051C) collided in orbit with the defunct Russian Kosmos 2251 satellite (93-036A). The collision occurred at 789 km altitude over the Siberian arctic, near 97.9 E, 72.5 N, with an orbital interception angle of 83.5 degrees. A cloud of rapidly spreading debris is now all that remains.

The collision occured at roughly the same altitude as the Chinese ASAT test on Fengyun 1C, and the resulting scenario for the debris cloud will be roughly similar to the latter event. An analysis of the Fengyun 1C debris field formation by Kelso can be read here.

COSMOS 2251 kollidierte am 10.02.2009 gegen 18:00H CET mit IRIDIUM 33. Dabei haben sich ca. 600 Trümmerteile entwickelt. Genaue Zahlen und Vektordaten stehen noch nicht fest. Sobald diese verfügbar sind, werden die Trümmer im obigen Bild in Pink dargestellt. Iridium 33 kann im MISSION CONTROl CENTER ausgewählt und verfolgt werden. COSMOS 2421, ein russischer Marineaufklärungssatellite erzeugt Trümmerteile. COSMOS 2421 bringt es auf ca. 508 katalogisierte Teile, davon sind ca. 48 im Orbit und 444 verglüht.

Über 600 Teile

http://seds.org/archive/spaceviews/9710/images2/iridium.jpg

Zerstörter Iridium-Satellit soll binnen 30 Tagen ersetzt werden.
Bei der Kollision zweier Satelliten hat sich ein riesiges Trümmerfeld gebildet, das möglicherweise für weitere Erdtrabanten gefährlich werden könnte.

Erste Radaruntersuchungen des US-Militärs haben ergeben, dass nach dem Zusammenstoß eines russischen Militärsatelliten mit einem US-Kommunikationssatelliten über 600 Trümmerteile zurückgeblieben seien.

Dabei handelt es sich laut NASA-Sprecher Michael Carey allerdings nur um eine erste grobe Schätzung. Genauere Daten seien erst in einigen Tagen zu erwarten, so Carey laut dem US-Sender CBS.

Radioaktive Strahlung
Während auch der russische Militärsprecher Alexander Jakuschin betonte, dass die Beschaffenheit der Trümmerwolke noch untersucht werden müsse, gab ein Weltraumexperte gegenüber der russischen Agentur Interfax zu bedenken, dass die Trümmer durchaus mit weiteren Satelliten zusammenstoßen könnten.

http://www.kbtm.ru/russian/news/image/cosmos3m_m.jpg

Eine Gefahr könnte etwa bei alten sowjetischen Spionagesatelliten entstehen, die Atombatterien an Bord haben. Bei einer Kollision mit Trümmerteilen könnten diese beschädigt werden und radioaktive Strahlung im All austreten, so der Experte weiter.

ISS-Ausweichmanöver notwendig?
Nach Ansicht des Sprechers der russischen Weltraumbehörde Roskosmos, Alexander Worobjow, bestehe allerdings für die Internationale Raumstation (ISS) "keinerlei Gefahr".

Die "Washington Post" zitierte indes ein NASA-Dokument, dem zufolge ein leicht erhöhtes Risiko für die ISS bestehe, von Satellitenschrott getroffen zu werden. Dieses Risiko halte sich aber "in akzeptablen Grenzen".

Die ISS befindet sich in nur 354 Kilometer Höhe, also deutlich unter dem Kollisionsorbit der beiden Unglückssatelliten. NASA-Sprecher John Yembrick sagte, der Schrott werde sich ausbreiten, weshalb die ISS möglicherweise ein Ausweichmanöver starten müsse. Dazu sei die Raumstation aber in der Lage, das sei ihr bereits in acht Fällen gelungen.

Spionagesatellit seit Jahren außer Betrieb
Der rund 900 Kilogramm schwere russische Satellit Kosmos-2251 der mit dem 560 Kilogramm schweren US-Satelliten Iridium-33 kollidiert war, war nach Angaben von Jakuschin seit 1993 im All und seit Jahren nicht mehr in Betrieb.

Der Aufprall ereignete sich bereits am Dienstag gegen 18.00 Uhr MEZ rund 800 Kilometer über Sibirien. Experten sprachen von einer einmaligen Kollision so großer Satelliten.

Nach Angaben des Deutschen Raumfahrt-Kontrollzentrums (DLR) in Oberpaffenhofen war es sogar der erste derartige Zwischenfall in der Geschichte der Raumfahrt. Die Wahrscheinlichkeit für einen Zusammenstoß zweier Satelliten sei "extrem gering", sagte DLR-Direktor Felix Huber der Nachrichtenagentur AFP.

3.000 Satelliten in Betrieb
Seit die Sowjetunion im Jahr 1957 mit Sputnik 1 den ersten künstlichen Flugkörper in eine Erdumlaufbahn gebracht hatte, wurden weltweit rund 6.000 Satelliten gestartet. Derzeit sind laut NASA-Angaben noch etwa 3.000 in Betrieb.

Ersatz binnen 30 Tagen
Die US-Betreiberfirma Iridium Satellite teilte indes mit, das der verloren gegangene Kommunikationssatellit binnen 30 Tagen durch einen bereits im All befindlichen Satelliten ersetzt werden soll. Zwischenzeitlich könne es zu kurzen Kommunikationsstörungen und -ausfällen kommen.

Nach eigenen Angaben betreibt Iridium Satellite ein Netzwerk von 66 Kommunikationssatelliten sowie mehreren Ersatzsatelliten im All. Die Firma betonte, die Kollision sei nicht auf technisches Versagen bei dem Iridium-Satelliten zurückzuführen.


U.S. And Russian Satellites Collide

Communications Satellite Hits Russian Satellite; International Space Station Deemed Safe


http://mek.kosmo.cz/druzice/usa/iridium/telefony.gif
Iridium World Phones

In an unprecedented space collision, a commercial Iridium communications satellite and a defunct Russian satellite ran into each other Tuesday above northern Siberia, creating a cloud of wreckage, officials said today. The international space station does not appear to be threatened by the debris, they said, but it's not yet clear whether it poses a risk to any other military or civilian satellites.

"They collided at an altitude of 790 kilometers (491 miles) over northern Siberia Tuesday about noon Washington time," said Nicholas Johnson, NASA's chief scientist for orbital debris at the Johnson Space Center in Houston. "The U.S. space surveillance network detected a large number of debris from both objects."

Air Force Brig. Gen. Michael Carey, deputy director of global operations with U.S. Strategic Command, the agency responsible for space surveillance, said initial radar tracking detected some 600 pieces of debris. He identified the Russian spacecraft as Cosmos 2251, a communications relay station launched in June 1993, and said the satellite is believed to have been non-operational for the past 10 years or so.

"As of about 12 hours ago, I think the head count was up (to around) 600 pieces," Carey told CBS News late today. "It's going to take about two days before we get a solid picture of what the debris fields look like. But you, I think, can imply that the majority of that should be probably along the same line as the original orbits."

He said U.S. STRATCOM routinely tracks about 18,000 objects in space, including satellites and debris, that are 3.9 inches across or larger. Tracking priority and "conjunction analysis" - identifying which objects may pose a threat to manned spacecraft - is the first priority.

"It's going to take a while" to get an accurate count of the debris fragments, Johnson said. "It's very, very difficult to discriminate all those objects when they're really close together. And so, over the next couple of days, we'll have a much better understanding."

Asked which satellite was at fault, Johnson said "they ran into each other. Nothing has the right of way up there. We don't have an air traffic controller in space. There is no universal way of knowing what's coming in your direction."

Iridium Satellite LLC operates a constellation of some 66 satellites, along with orbital spares, to support satellite telephone operations around the world. The spacecraft, which weigh about 1,485 pounds when fully fueled, are in orbits tilted 86.4 degrees to the equator at an altitude of about 485 miles. Ninety-five Iridium satellites were launched between 1997 and 2002 and several have failed over the years.

"Yesterday, Iridium Satellite LLC lost an operational satellite," the company said in a statement. "According to information shared with the company by various U.S. government organizations that monitor satellites and other space objects (such as debris), it appears that the satellite loss is the result of a collision with a non-operational Russian satellite.

"Although this event has minimal impact on Iridium’s service, the company is taking immediate action to address the loss. The Iridium constellation is healthy, and this event is not the result of a failure on the part of Iridium or its technology. While this is an extremely unusual, very low-probability event, the Iridium constellation is uniquely designed to withstand such an event, and the company is taking the necessary steps to replace the lost satellite with one of its in-orbit spare satellites."

Johnson said the collision was unprecedented.

"Nothing to this extent (has happened before)," he said. "We've had three other accidental collisions between what we call catalog objects, but they were all much smaller than this and always a moderate sized objects and a very small object. And these are two relatively big objects. So this is a first, unfortunately."

As for the threat posed by the debris, Johnson said NASA carried out an immediate analysis to determine whether the space station faced any increased risk. The station, carrying three crew members, circles the globe at an altitude of about 220 miles in an orbit tilted 51.6 degrees to the equator.

"There are two issues: the immediate threat and a longer-term threat," he said. "It turns out, when you have a collision like this the debris is thrown very energetically both to higher orbits and to lower orbits. So there are actually debris from this event which we believe are going through the space station's altitude already. Most of it is not, most of it is still clustered up where the event took place. But a small number are going through station's altitude.

"Yesterday, we did an assessment of what the risk might be to station and we found it's going to be very, very small. As time goes on, those debris will (come down) some over months, most over years and decades and as the big ones come down they'll be tracked, we'll see them and the worst-case scenario, we'll just dodge them if we have to. It's the small things you can't see are the ones that can do you harm."

Asked if other satellites might be at risk, Johnson said "technically, yes. What we're doing now is trying to quantify that risk. That's a work in progress. It's only been 24 hours. We put first things first, which is station and preparing for the next shuttle mission."

Most, if not all, of the debris is expected to eventually burn up in Earth's atmosphere.

THIS WAS THE WASHINGTON POST ARTICLE... NOT A GOOD INFORMATION SOURCE.

http://mek.kosmo.cz/druzice/usa/iridium/iridiumm.jpg
The Iridium satellite constellation is a system of 66 active communication satellites with spares in orbit and on the ground. It allows worldwide voice and data communications using handheld satellite phones. The Iridium network is unique in that it covers the whole Earth, including poles, oceans and airways.

The company, based in Bethesda, Maryland, United States, derives its name from the chemical element iridium. The number of satellites projected in the early stages of planning was 77, the atomic number of iridium, evoking the metaphor of 77 electrons orbiting the nucleus.

Iridium communications service was launched on November 1, 1998. The first Iridium call was made by then-Vice President of the United States Al Gore. Motorola provided the technology and major financial backing.

The founding company went into Chapter 11 bankruptcy nine months later, on August 13, 1999. The handsets could not operate as promoted until the entire constellation of satellites were in place, causing a massive initial capital cost running into the billions of dollars. The increased coverage of terrestrial cellular networks, e.g., GSM, and the rise of roaming agreements between cellular providers proved to be fierce competition. The cost of service was prohibitive for many users, and the bulkiness and expense of the hand held devices when compared to terrestrial cellular mobile phones discouraged adoption among potential users.

Mismanagement has also been cited as a major factor in the original program's failure. In 1999, CNN writer David Rohde detailed how he applied for Iridium service and was sent information kits, but was never contacted by a sales representative. He encountered programming problems on Iridium's Web site, and a "run-around" from the company's representatives. After Iridium filed bankruptcy, it cited "difficulty gaining subscribers".

The initial commercial failure of Iridium had a dampening effect on other proposed commercial satellite constellation projects, including Teledesic. Other schemes (Orbcomm, ICO Global Communications, and Globalstar) followed Iridium into bankruptcy protection, while a number of other proposed schemes were never constructed.

At one stage there was a threat that the Iridium satellites would have to be de-orbited; however, they remained in orbit and operational. Their service was restarted in 2001 by the newly founded Iridium Satellite LLC, which was owned by a group of private investors. Although the satellites and other assets and technology behind Iridium were estimated to have cost on the order of US$6 billion, the investors bought the firm for about US$25 million.

On February 10, 2009, Iridium 33 collided with a defunct Russian satellite, Cosmos-2251, 500 miles over Siberia. A pair of massive debris clouds was created

Present status

Iridium Satellite LLC has 280,000 subscribers as of early August 2008 (compared to 203,000 in July 2007). Revenue for the second quarter of 2008 was US$81.7 million with EBITDA of US$25.8 million.

The system is being used extensively by the U.S. Department of Defense through the DoD gateway in Hawaii. The DoD pays $36 million a year for unlimited access for up to 20,000 users. An investigation was begun into the DoD contract after a protest by Globalstar, to the U.S. General Accounting Office that no tender was provided. The investigation was suspended at the request of the Pentagon, who cited national security reasons.

The commercial gateway in Tempe, Arizona, provides voice, data, and paging services for commercial customers on a global basis. Typical customers include maritime, aviation, government, the petroleum industry, scientists, and frequent world travelers.

Iridium satellites are now an essential component of communications with remote science camps, especially the Amundsen-Scott South Pole Station. As of December 2006, an array of twelve Iridium modems was put online, providing continuous data services to the station for the first time. Total bandwidth is 28.8 kbit/s.

Phone numbers

Iridium controls the virtual country codes +8816 and +8817, part of the 881 range designated by the ITU for the Global Mobile Satellite System. Each subscriber is given an 8-digit number prefixed by one of these country codes

The Iridium system requires 66 active satellites in orbit to complete its constellation, with spare satellites in-orbit to serve in case of failure. Satellites are in low Earth orbit at a height of approximately 485 miles (780 km) and inclination of 86.4°. Orbital velocity of the satellites is approximately 17,000 mph (27,000 km/h). Satellites communicate with neighboring satellites via Ka band intersatellite links. Each satellite can have four intersatellite links: two to neighbors fore and aft in the same orbital plane, and two to satellites in neighboring planes to either side. The satellites orbit from pole to pole with an orbit of roughly 100 minutes. This design means that there is excellent satellite visibility and service coverage at the North and South poles, where there are few customers. The over-the-pole orbital design produces a "seam" where satellites in counter-rotating planes next to one another are travelling in opposite directions. Cross-seam intersatellite-link handoffs would have to happen very rapidly and cope with large Doppler shifts; therefore, Iridium supports intersatellite links only between satellites orbiting in the same direction.

Satellites

The satellites each contain seven Motorola/Freescale PowerPC 603E processors running at roughly 200 MHz. Processors are connected by a custom backplane network. One processor is dedicated to each cross-link antenna ("HVARC"), and two processors ("SVARC"s) are dedicated to satellite control, one being a spare. Late in the project an extra processor ("SAC") was added to perform resource management and phone call processing.

The cellular look down antenna has 48 spot beams arranged as 16 beams in three sectors. The four inter-satellite cross links on each satellite operate at 10 Mbit/s. The inventors of the system had previously worked on a government study in the late 1980s that showed that microwave cross links were simpler and had fewer risks than optical cross links. Although optical links could have supported a much greater bandwidth and a more aggressive growth path, microwave cross links were favored because the bandwidth was more than sufficient for the desired system. Nevertheless, a parallel optical cross link option was carried through a critical design review, and ended when the microwave cross links were shown to support the size, weight and power requirements allocated within the individual satellite's budget. In recent press releases, Iridium Satellite LLC has stated that their second generation satellites would also use microwave, not optical, inter-satellite communications links. Such cross-links are unique in the satellite telephone industry, as other providers do not relay data between satellites.

The original design envisioned a completely static 1960s "dumb satellite" with a set of control messages and time-triggers for an entire orbit that would be uploaded as the satellite passed over the poles. It was found that this design did not have enough bandwidth in the space-based backhaul to upload each satellite quickly and reliably over the poles. Therefore, the design was scrapped in favor of a design that performed dynamic control of routing and channel selection late in the project, resulting in a one year delay in system delivery.

Each satellite can support up to 1100 concurrent phone calls and weighs about 1,500 pounds (700 kg). The vast majority of patents filed by Motorola during the Iridium project concern ways to manufacture and launch satellites affordably. The satellites were designed to mount sideways on a gimbal for easy access during manufacture (most satellites up until that time had been assembled vertically.) Motorola hired the chief manufacturing engineer from Apple Computer, who had set up the first Macintosh manufacturing line, to help design and automate satellite production.

In-orbit spares

Spare satellites are usually held in a 667 kilometres (410 mi) storage orbit. These will be boosted to the correct altitude and put into service in case of a satellite failure. Many satellites have failed over the years, the most recent being Iridium 28 which failed in July 2008, and Iridium 33 which collided with the defunct Russian satellite, Cosmos-2251, on February 10, 2009. Currently, there appear to be seven spares in orbit, along with several partially failed satellites that are not in active service. Five non-functional satellites have also reentered the Earth's atmosphere.

Zitat:
Radon ist ein geruch- und farbloses, radioaktives Gas natürlichen Ursprungs, das aus dem Untergrund an die Erdoberfläche gelangt und sich dort in Gebäuden ansammeln kann. Radon ist ein Zerfallprodukt des Urans, dessen natürliches Vorkommen in allen Gesteinsformationen in unterschiedlicher Menge festgestellt wird. In einigen Gegenden, insbesondere in jenen mit schieferhaltigem Untergrund, können die Radonkonzentrationen ein gesundheitsschädliches Niveau erreichen.
Das Einatmen von Radon erhöht das Lungenkrebsrisiko. Das Risiko erhöht sich mit zunehmenden Konzentrationen und der Aufenthaltsdauer in den mit Radon belasteten Gebäuden. Eine Reihe von Untersuchungen hat gezeigt, dass Radon die zweitwichtigste Lungenkrebsursache nach dem Rauchen ist. Es stehen jedoch einfache und preisgünstige Verfahren zur Verfügung, um die Radonkonzentrationen in den Wohnräumen zu senken und so die Auswirkungen des Radons auf die Gesundheit mit geringem Aufwand zu reduzieren.
Deshalb ist es wichtig:
1. die Radonkonzentrationen in Ihrem Haus zu kennen;
2. sich genau über mögliche Maßnahmen zur Reduzierung der Radonkonzentration und über eventuelle
Präventionsmaßnahmen zu informieren.


Radon lässt sich in Ihrem Haus leicht messen. Meistens genügt eine Messung in dem am stärksten genutzten Wohnraum. Das Messverfahren ist für die Gesundheit vollkommen unbedenklich. Die Messung erfolgt mit einem passiven Detektor, der einer Konservendose ähnelt und der die Radonpartikel registriert. Sie stellen diesen Detektor während 3 Monaten in dem am stärksten genutzten Wohnraum im Erdgeschoss Ihres Hauses auf, beispielsweise auf einem Schrank. Nach dieser Registrierperiode wird dann die Radonkonzentration im Labor festgestellt. Einige Wochen später wird Ihnen die Radonbelastung Ihres Hauses mitgeteilt, mit Empfehlungen für eventuelle Reduzierungsmaßnahmen. Sollte die Radonkonzentration den Referenzwert von 400 Bq/m³ übersteigen, so führt die Föderale Agentur für Nuklearkontrolle kostenlos zusätzliche Messungen durch, um die Infiltrationsquelle zu ermitteln und unterstützt Sie bei der Behebung des Problems.

Radioaktivität selbst messen

Direkt zu den aktuellen Messdaten in Offenburg

Da Regierungsstellen (und teilweise auch Großunternehmen) uns häufig belügen und undurchsichtigen Interessen folgen, gibt es gute Gründe, die Radioaktivität in der Umwelt selbst zu messen, um bei letztlich jederzeit durch menschliches, technisches oder organisatorisches Versagen möglichen Katastrophen (Kernschmelze wie in Tschernobyl oder Krieg) und Störfällen besser informiert zu sein und im betreffenden Einzugsbereich ggf. eine größere Vorwarnzeit für den persönlichen und kollektiven Strahlenschutz bzw. Katastrophenschutz nutzen zu können.

Nicht nur in Russland wurde die Bevölkerung bei der Tschernobyl-Katastrophe im Jahr 1986 zunächst über vieles im Unklaren gelassen. Im Elsass, dem französischen Departement in Nachbarschaft zu Baden-Württemberg, ist damals jedem aufgefallen, dass die deutschen Medien vor der Radioaktivität warnten, die französischen jedoch abwiegelten, als ob die vom Wind verteilte Radioaktivität an der Grenze plötzlich halt machte. Aber auch in Deutschland wurden auf heimliche oder diktatorische Weise Daten unterdrückt.

Da die Strahlung von radioaktiven Elementen mit kurzer Halbwertszeit schnell abklingt, liegt gerade zu Beginn eines Störfalls, bei dem ein Gemisch radioaktiver Elemente austritt, eine hohe Radioaktivität vor. Somit ist es wichtig, schnell über Störfälle informiert zu werden, um entsprechende Schutzmaßnahmen ergreifen zu können.

Die normalerweise eingesetzte technische Vorrichtung zum Messen von Radioaktivität wird nach dem Erfinder als Geigerzähler bezeichnet. In diesen Geräten werden Geiger-Müller-Zählrohre eingesetzt, die beim Eintreffen eines Strahlenphotons oder -teilchens einen elektrischen Impuls erzeugen, der dann gemessen, registriert und ausgewertet werden kann. Da Geigerzähler bzw. Geiger-Müller-Zählrohre sowie Elektronikschaltungen und Computer heute relativ preisgünstig erhältlich sind, ist der Selbstbau von Mess- und Auswertungsvorrichtungen für Radioaktivität heute auch für Privatleute ohne großen Aufwand möglich, und das Internet gibt uns Echtzeit-Präsentations- und Vernetzungsmöglichkeiten, sodass die Daten auch größeren Personenkreisen zugänglich gemacht werden können.


Entwicklungsziele

Auf diesen Seiten soll der Aufbau einer solchen Radioaktivitäts-Messstation vorgestellt werden.

Dabei standen folgende Ziele im Vordergrund:

  • Geringer Preis.
  • Mit Hobbymitteln (oder semiprofessionellen Mitteln) realisierbar.
  • Einfacher Aufbau.
  • Flexible Auswertungsmöglichkeiten.
  • Warnmöglichkeit bei Überschreiten von Schwellenwerten.
  • Vernetzung.

Es wäre sicher nützlich, regionale Umweltmessgruppen aufzubauen. Vielleicht kennen Sie jemanden, der dabei behilflich sein möchte, vielleicht haben sie ein Unternehmen, das Mittel oder Know-how dafür bereitstellen möchte, vielleicht haben Sie selbst Lust dazu. Nähere Informationen dazu hier.

Ansonsten folgen hier jetzt eher technische Informationen.


Hardware

In meinem eigenen Aufbau kommt ein Radioaktivitäts-Messgerät zum Einsatz, das ich für wenige Euro bei ebay gekauft habe. Da es sich um ein eigenständig zu betreibendes Gerät handelt, habe ich eine aus nur wenigen Bauteilen bestehende, selbst entwickelte Schnittstelle für den Anschluss an den Computer nachgerüstet. Das war für mich die kostengünstigste Lösung, und sie war auch am schnellsten zu realisieren, da ich wegen des Einsatzes von Bauteilen aus der Bastelkiste auf keinerlei Lieferungen warten musste.

Der Name des Geräts ist "Pripjat", dies ist die in ca. 4 km Entfernung von Tschernobyl gelegene Stadt, in der die Familien der Arbeiter des Kraftwerks lebten und die heute eine Geisterstadt ist. Der angezeigte Wert ist ein normaler Wert der Hintergrundstrahlung (dieser entspricht jedoch nicht den in den Grafiken dargestellten Impulsen/Minute). Oben links der Klinkenstecker für das Kabel zum Computer, unten rechts der Netzteilanschluss. (Wegen der beengten Platzverhältnisse im Gerät ließ sich leider keine günstigere Anordnung finden.)



Das Deckblatt der mitgelieferten Beschreibung:



Diese Beschreibung enthält glücklicherweise den Schaltplan des Geräts (für großen Schaltplan anklicken - wird in neuem Fenster geöffnet):

Und hier die Interface-Schaltung, mit der der Geigerzähler an die serielle Schnittstelle des Computers angeschlossen wird. Der Optokoppler (Isolationsspannung 5000 Volt) dient der galvanischen Trennung zum Schutz des Geigerzählers als auch des Computers (Zählrohre werden üblicherweise mit Hochspannung zwischen 350 und 700 Volt betrieben!), falls eines der Geräte ausfallen oder falsch angeschlossen werden sollte. Die Diode an der rechten Seite des Optokopplers dient der Spannungsbegrenzung, solange der DTR-Ausgang der seriellen Schnittstelle nicht positiv geschaltet ist, da die Spezifikation des Optokopplers nur eine Spannung von 5 Volt erlaubt, wenn der Emitter positiver ist als der Kollektor des Phototransistors.
Der Eingang (ganz links) wird an dem im Geräteschaltplan mit (3) bezeichneten Punkt (Ausgang von Df.1/Eingänge von Df.2) angeschlossen, wo der Impuls sauber geformt ungefähr mit TTL-Pegel zur Verfügung steht (siehe Kurven ganz links unten im Geräteschaltplan). Die Versorgungsspannungen werden ebenfalls an geeigneten Punkten des Geräts abgegriffen (z.B. an den Pins 7 (Masse) und 14 (+5 Volt) von IC "Df"). Ein ähnlicher Anschluss dürfte auch bei vielen anderen Geräten möglich sein.
Außerdem wurde die rechte Seite von Schalter S2 (d.h. Punkt KT4), der die hörbaren Lautsprecherimpulse des Geräts abschaltet, von C5/R8 getrennt und stattdessen an die Basis von VT4 angeschlossen. Somit lässt sich nach wie vor der interne Lautsprecher abschalten, dabei werden aber weiterhin von Df.1 und Df.2 die Impulse gebildet, die über die Interface-Schaltung zum Computer herausgeführt werden.
Eine Buchse zum Anschluss einer stabilisierten Versorgungsspannung von 9V (passendes Steckernetzteil, statt einer Blockbatterie) wurde ebenfalls ins Gerät eingebaut und über eine Diode verpolungssicher ausgeführt. (Nicht im Schaltplan dargestellt.)
Der DTR-Ausgang (Data Terminal Ready) der seriellen Schnittstelle des Computers wird vom Treiber ständig auf einen positiven Wert gezogen und liegt über den Widerstand am RI-Eingang (Ring Indicator) der seriellen Schnittstelle, der von jedem Zählimpuls über den Optokoppler auf Masse gezogen wird. Diese Impulse werden vom Treiber gezählt und von anderen Programmen weiterverarbeitet (s.u.). Das Schalten gegen Masse entspricht zwar nicht den RS-232-Spezifikationen, scheint normalerweise aber zu funktionieren.




Der Innenbaufbau mit den Kabeln meiner Zusatzschaltungen. Die rosafarbenen Kabel gehören zum Gerät, die anderen sind von mir. Links unten ist eine kleine Lochrasterplatine zu sehen, auf der das Interface aufgebaut wurde und die mit Styroporstücken befestigt (eingeklemmt) ist; daneben sind die 3,5-mm-Klinkenbuchse für den Anschluss zum Computer und die Kontroll-LED zu sehen.



Dieses Bild zeigt die Buchse und die LED bei geschlossenem Gehäuse:



Andere Bezugsquellen für Geiger-Müller-Zählrohre:

Bei einer Internetrecherche ist mir das US-Unternehmen Aware-Electronics (http://www.aw-el.com/) aufgefallen, bei dem Zählrohre mit einer einfachen Elektronik in Kunststoffgehäusen erhältlich sind, die über ein ggf. recht langes Kabel direkt an die Schnittstelle des Computers angeschlossen werden können. Die Geräte besitzt keinerlei Anzeige- oder Auswertungselektronik, sondern liefern nur die Impulse. Preis für das fertige, kalibrierte und einsatzbereite Gerät nach Europa (inkl. Versand): ab ca. 180 Euro (Juni 2005). (Anmerkung: Ich benutze dieses Gerät selbst nicht und erhalte keine Provisionen von der Firma.)

Es gibt auch fertige Geräte, die z.B. bei Conrad-Elektronik bezogen werden können.

Software

Software zum Zählen der Impulse und zum Aufzeichnen (Loggen) der Daten

Zunächst ist die Umwandlung der über die Schnittstelle des Computers eintreffenden Impulse des Geiger-Müller-Zählrohrs in ein einheitliches Datenformat notwendig.

Rik Faith hat ein Linux-Programm zum Zählen von über die serielle Schnittstelle eingespeisten Impulsen mit dem Namen "geiger.c" geschrieben, das im Internet für alle zur Verfügung steht. Dieses Programm zählt die Impulse am Eingang RI (Ring Indicator) der als Parameter angegebenen seriellen Schnittstelle (z.B. /dev/ttyS0) und gibt diese in im Programm eingestellten Intervallen auf der Konsole aus. Die Ausgabe kann, wie bei *nix-Systemen üblich, in eine Datei oder eine Pipe umgeleitet werden. Das Programm kann natürlich auch als Hintergrund-Task laufen und bei entsprechender Konfiguration beim Hochfahren des Systems gestartet werden, sodass möglichst lückenlose Datenprotokolle erstellt werden können. Das Programm ist unter der URL http://www.aw-el.com/linux1.txt (von dieser Website, leicht angepasste Version) verfügbar, sollte aber je nach eingesetztem Geiger-Müller-Zählrohr noch an die eigenen Bedürfnisse angepasst werden (Kalibrierungsfaktor).

Die Kompilierung des Programms "geiger.c" zum ausführbaren Programm "geiger" erfolgt auf einem debian-System mit dem folgenden Befehl:

gcc -wALL -I/usr/include -ogeiger geiger.c

WICHTIG: Im Programm ist ein Kalibrierungsfaktor von 1,05 (im Programm angegeben als "1000.0 / 1050.0") voreingestellt, der nur für ein bestimmtes Gerät gilt. Zum einfachen, unveränderten Messen der Impulse muss dieser Faktor auf 1 gesetzt werden.

Bei anderen Systemen muss ggf. das Verzeichnis für die Include-Dateien angepasst werden.

Weitere (noch experimentelle) Software, u.a. zum Aufzeichnen der Daten in einer MySQL-Datenbank, findet man unter diesem Projekt bei SourceForge: http://geiger.sourceforge.net/.

Nützliche Befehle:

Hier sind einige nützliche Befehle für die Eingabe an der Konsole aufgeführt, mit denen dieses Programm genutzt werden kann.

  • Programm starten, Impulse von der seriellen Schnittstelle Nr.1 einlesen und Daten auf der Konsole ausgeben:

    ./geiger -t /dev/ttyS0

    Auf der Konsole erscheint dann folgende Ausgabe:

    1120553367 31.0 29.0 # Tue Jul  5 10:49:27 2005
    1120553427 28.0 28.8 # Tue Jul 5 10:50:27 2005
    1120553487 29.0 28.2 # Tue Jul 5 10:51:27 2005
    1120553547 40.0 31.6 # Tue Jul 5 10:52:27 2005

    Das erste Feld enthält die Unix-Timestamp (Zahl von Sekunden nach dem 1.1.1970 0.00 Uhr), das zweite Feld den aktuellen Messwert, das dritte Feld einen Mittelwert über die letzten Minuten, dann kommt noch ein "#" und der Zeitpunkt in direkt menschenlesbarer Form. Über welche Zeit jeweils gemessen wird, kann im Quellcode des Programms eingestellt werden. Vorgegeben sind Messung über 1 Minute und Mittelung über 5 Minuten.

  • Programm starten, Impulse von der seriellen Schnittstelle Nr.1 einlesen, Daten auf der Konsole ausgeben und gleichzeitig in Datei "test.log" loggen:

    ./geiger -t /dev/ttyS0 | tee test.log

    Neben der Aufzeichnung in der angegebenen Datei erscheint auf der Konsole gleichzeitig wieder die oben gezeigte Ausgabe.

  • Umformatierung der Protokolldatei test.log in eine CSV-Datei "log.csv". Dabei werden nur die Timestamp (erstes Feld) und der jeweilige Impulswert (zweites Feld) berücksichtigt:

    awk 'BEGIN {FS=" "} {print $1 "," $2 }' test.log > log.csv

    Die Datei log.csv enthält dann Zeilen folgender Art:

    1120553367,31.0
    1120553427,28.0
    1120553487,29.0
    1120553547,40.0
  • Etwas Ähnliches erreicht man übrigens mit dem Befehl:

    cut -d" " -f1,2 test.log
  • Schreibt man den Befehl etwas um:

    awk 'BEGIN {FS=" "} {print "\"" $1 "\",\"" $2 "\""}' test.log > log.csv

    erhält man folgende Einträge:

    "1120553367","31.0"
    "1120553427","28.0"
    "1120553487","29.0"
    "1120553547","40.0"
  • Will man in der Ausgabe keine Punkte, sondern Kommata haben, schreibt man:

    awk 'BEGIN {FS=" "} {print "\"" $1 "\",\"" $2 "\""}' test.log | sed 's/\./,/g' > log.csv

    Die Einträge in der Datei lauten dann:

    "1120553367","31,0"
    "1120553427","28,0"
    "1120553487","29,0"
    "1120553547","40,0"

    Das sollte sich problemlos in (deutsche) Tabellenkalkulationsprogramme importieren lassen.

Software zur Auswertung und Darstellung

Die reinen Datenreihen sind etwas langweilig und geben keinen guten Überblick über die Radioaktivitätslage. Daher sind Auswertungs- und Darstellungsprogramme notwendig, möglichst natürlich mit grafischer Anzeige als Diagramme.

Dazu können einfache Scripte oder ausgewachsene Auswertungssysteme programmiert werden. Da ich damit noch nicht weit genug bin, kann ich hier auch noch nicht viel davon berichten. Es sei nur soviel gesagt, dass man mit Tabellenkalkulationen und Programmen wie rlplot schnell erste Ergebnisprototypen erzielen kann.

Ein einfaches Programm zur Anzeige der Zahlen als Balken auf der Konsole ist folgendes Python-Script "bargraph.py":

#!/usr/bin/python

import sys

pipe=open(sys.argv[1],'r')

while True:
print "*" * int(float(pipe.readline().split(' ')[1]))

Um es zu nutzen, muss die Ausgabe des Programms "geiger" in eine Pipe (hier: "geigerpipe") geleitet werden, die dann mit folgendem Befehl fortlaufend ausgelesen und ASCII-grafisch dargestellt wird:

./bargraph.py geigerpipe

Beispiel für die Ausgaben, die von unten nach oben durchs Fenster laufen:

*****************************
***********************************
****************************
*******************************

*********************************

***************************
*****************************************

Hier sind noch zwei Beispiele für Diagramme, die mit der Tabellenkalkulation mit OpenOffice.org erstellt wurden. Zuerst die Rohdaten (eine Punktwolke -- die Streuung ist normal, da Radioaktivität der Theorie gemäß eine gewisse Zufallsverteilung besitzt) und dann gemittelte Werte (gleitender Mittelwert über jeweils 60 Werte, d.h. 1 Stunde) einer Messreihe mit mehr als 800 Punkten; dargestellt sind die Impulszahl pro Minute über der Timestamp:





Hier noch eine Grafik, die mit drei Testpräparaten mit unterschiedlichen Impulsraten aufgenommen wurde, die sich deutlich von der Hintergrundstrahlung absetzen (diese Messungen wurden am Vormittag des 18.7.2005 durchgeführt und sind in der entsprechenden Archivgrafik sichtbar). Diese Grafik wurde mit dem äußert praktischen Programm gnuplot erstellt. Nach dem Start von gnuplot wird einfach folgender Befehl gegeben und dann ein geeigneter Ausschnitt mit der Maus gewählt (Rechtsklick und Ausschnitt aufziehen):

gnuplot> plot "/test.log" with lines


Sollen stattdessen die 5-Minuten-Mittelwerte dargestellt werden, verwendet man diesen Befehl (Auswahl des ersten und des dritten Felds der Datei statt der Standardauswahl):

gnuplot> plot "/test.log" using 1:3 with lines

Hier die drei Testpräparate. Es handelt sich um natürlicherweise radioaktive Steine (sog. Stufen). Die Messwerte sind vom Verkäufer der Stufen direkt am Stein ermittelt worden. Die Reihenfolge entspricht der Reihenfolge der Peaks in der vorstehenden Grafik:

Uraninit, Curit, Wölsendorfit, Fourmarierit (Wölsendorf) Euxenit (Betsiboka in Madagaskar) Fergusonit-Y (Iveland, Norwegen)
19,0 µSv/h 2,0 µSv/h 0,7 µSv/h

Weitere Möglichkeiten:

Automatisches Hochladen von Messwertreihen und Diagrammen auf einen Webserver. Die von meiner Messvorrichtung gemessenen Daten sind hier verfügbar. Ein anderes Beispiel für automatisch erstellte Echtzeit-Diagramme auf einem Webserver befindet sich hier: http://alephnull.com/mrtg/geiger.html.

E-Mail-Rundschreiben. Die Daten können automatisch per E-Mail an Empfängerlisten versandt werden. Dies kann entweder immer geschehen, um aus Redundanzgründen Kopien der Messreihen zu versenden, oder die Daten können, ggf. zusammen mit je nach Werten abgestuften Warnhinweisen und Erklärungen, nur beim Überschreiten von Schwellenwerten automatisch versandt werden. Die Eintragung in die Empfängerliste kann zum Beispiel über ein öffentlich zugängliches Webformular erfolgen. Bei großer Zahl von Empfängern ist wegen der für den Versandt notwendigen Zeit zu überlegen, ob die Warnungen überhaupt noch in Echtzeit bei den Empfängern eintreffen. Die Bandbreite der Internetanbindung und die Anzahl gleichzeitig versendbarer E-Mails spielen dabei möglicherweise eine Rolle, und vielleicht ist sogar ein Kaskadensystem mit mehreren Teilnehmern notwendig.

Gleichzeitige Aufzeichnung von Radioaktivitätsmesswerten und GPS-Daten. Dafür hat jemand ein Perl-Script geschrieben: http://ian.kluft.com/opensource/code/gps-geiger-0.2.pl. Damit lassen sich bei Einsatz eines Notebooks und Datenerfassung im Gelände Radioaktivitätskarten erstellen.

Anbindung des Geiger-Müller-Zählrohrs als Entropiequelle für kryptographische Zwecke. Sollte ohne große Schwierigkeiten möglich sein, aber ich habe leider kein konkretes Anwendungsbeispiel dafür.

Hinweise zur Messung

Ich habe festgestellt, dass die Zahl der pro Minute gemessen Impulse von der Richtung der Geiger-Müller-Zählrohre abhängt. Wenn die Zählrohre horizontal (liegend) ausgerichtet sind, werden etwas mehr Impulse gemessen, als wenn sie senkrecht (stehend) ausgerichtet sind. Daher sollte das Gerät im Interesse vergleichbarer Messdaten immer gleich positioniert bleiben.

Meine derzeitige Vermutung für die Ursache des gerichteten Strahlenfeldes ist, dass aus dem Weltraum kommenden Gammastrahlen (die von der Erde zumindest teilweise abgeschirmt werden) bei liegenden Zählrohren aufgrund der vom Himmel aus gesehen größeren Querschnittsfläche stärker ins Gewicht fallen, während die in der Luft mitgeführte Radioaktivität das Gerät gleichmäßig umgibt.

Mitmachen: Messstellen vernetzen!

Das Wissen über einen Anstieg der Radioaktivität am eigenen Wohnort ist schon eine nützliche Information mit -- je nach Sachlage -- beruhigender oder beunruhigender Wirkung. Um noch mehr Informationen über Freisetzungen radioaktiven Materials aus kerntechnischen Anlagen oder Transportbehältern zu erfahren, ist es sinnvoll, eine ungefähre Identifizierung der Position einer Radioaktivitätsquelle zu ermöglichen. Dies kann dadurch erreicht werden, dass viele Messstellen an verschiedenen Orten eingesetzt und die Daten miteinander vernetzt werden (verschiedene Überlegungen dazu hier). Dies hat den Vorteil, dass man bei genügender Zahl von Messstellen relativ leicht (d.h. ohne im Gelände herumfahren zu müssen) Karten über die Radioaktivitätsverteilung erstellen kann, anhand derer sich neben der Lokalisierung des Ursprungs auch die Ausbreitung freigesetzten Materials verfolgen lässt. Ein weiterer Vorteil ist, dass ein größerer Personenkreis mit der Messung von Radioaktivität vertraut wird und eine Unterbindung der Messdatenerfassung durch bürgerfeindliche Elemente erschwert wird.

Eine andere Möglichkeit besteht darin, die Radioaktivitätsmessstation mit Messvorrichtungen für Windrichtung und Windgeschwindigkeit auszustatten und diese Daten gleichzeitig zu protokollieren, was allerdings den mechanischen und sensortechnischen Aufwand vergrößert.

Um die Daten von unterschiedlichen Messorten miteinander vergleichen zu können, ist natürlich notwendig, die für die Zeitprotokollierung verwendeten Uhren korrekt zu stellen (NTP, DCF77 o.ä.).

Schlusswort

Ich hoffe, diese Seite regt Sie an, ihr Leben wieder stärker selbst in die Hand zu nehmen und mit anderen an der Organisation der Gesellschaft mitzuarbeiten, anstatt die Verantwortung für die Gemeinschaft Politikern, Ämtern und Unternehmen zu überlassen, die uns viel zu oft enttäuschen, ihre Funktionen missbrauchen bzw. nicht ausreichend erfüllen und uns das Leben schwer machen. Irgendwelche Leute mit einer zu großen Machtfülle auszustatten, ist noch nie sonderlich ratsam gewesen (siehe dazu z.B. das Kapitel "1. Samuel 8/10-19" in der Bibel), und wenn man sieht, in welche Kalamitäten (Kriege, Hungernöte usw.) uns die Machtpolitik auf dem ganzen Planeten im 20. Jahrhundert (und danach) gestürzt hat, so ist es ganz offensichtlich höchste Zeit, dass die Bürger ihre Geschicke wieder selbst übernehmen.

This is the most sophisticated personal geiger counter/radiation monitor in our current range. It is extremely sensitive, easily registering natural background radiation, and highly accurate, with the 42mm backlit LCD panel giving constantly updated and averaged readings (in 10 second cycles) of exposure to a wide range of Beta and Gamma radiation. It is calibrated in micro Sieverts or micro Rem per hour, switchable using the on-screen menu. This also controls the variable volume bleeper and setup options, plus a level control which lets you program the bleeper threshold to 0.3, 0.6 or 1.2 uSv/hr (30, 60 or 120 uRem/Hr).

The RD 1503 is sturdy, very well built, and remarkably easy to use, with just three buttons, for switching the unit on and off, switching the backlight on and navigating the on-screen menus. It’s compact too, measuring just 100 x 60 x 24mm – around the size of a pack of 20 cigarettes -- and it weighs just 90 grams, so it slips easily into shirt or trouser pockets. It is powered by one or two AAA cells, which can run the unit continuously for up to 550 hours (over 3 weeks!).

For the technically minded the range of measurement is from 0.05 to 9.99uSv/Hr (5 – 999 uRem/hr) and the gamma range is 0.1 to 1.25MeV.







Built to military spec and featuring twin Geiger-Muller tube detectors this is one of the most sensitive models in our range, reacting to beta and gamma radiation from 0.003 microsievert, clicking between 10 and 50 times a second in response to background radiation. It has visual and audible indicators plus a extra red high level activity warning LED. The case measures 150 x 65 x 22mm and a pair of AA batteries will last for 100 hours or more. NB: card not included (display only)

VERY LIMITED STOCKS - ONCE THEY'RE GONE, THAT'S IT

Ideal for budding Nuclear Physicists and keeping watch on your local environment. This Russian made Dosimeter or Geiger Counter is about the size of a skinny cellphone. It has both audible and visual indicators; it detects normal background radiation (beta and gamma, from 0.003 microsievert) clicking and flashing between 1 - 20 times a minute, depending on local conditions. It has a simple on-off control and is fitted with a belt pocket clip. It measures approximately 133 x 23 x 35mm and runs for a week or more on a single AA battery (supplied).

This version, exclusive to anythingradioactive, is fitted with a PC interface so you can plug it into your computer. The FREE software from our web site turns it into a proper Geiger Counter and displays the results on your PC or laptop screen.

The counting and data logging software shows actual counts per minute (CPM), total count and this can be calibrated to display milliRontgens/hr (mR/hr). The results are also presented on a customisable real-time graph, Additionally the data can be stored, to produce a detailed log, providing unlimited integration times, so you can measure really low levels of activity. The program also includes a web server, so results can be monitored remotely via a standard web browser.

The DSRB-88B comes complete with the custom PC interface, 3 metre connecting lead, and a link to the software download. Please note the software presently runs on PCs with Windows 95, 98, ME, SE, NT4, 2k and XP, a soundcard and Internet Explorer v6 or later is also required; sorry no MAC, Linux or Vista versions yet, but we’re working on it.

ONLY A FEW LEFT -YOUR LAST CHANCE TO OWN ONE OF THESE

Here’s something really different and very special. It’s a tiny Russian Geiger Counter that fits on a key ring. It’s a brilliant design, very sensitive and it responds to background and elevated levels of ionising radiation (beta and gamma). In normal use it ‘ticks’ quietly a couple of times each second, to let you know that it is working and all is well, but as soon as it detects any radioactivity the red LED on the top flashes and it emits a warning bleep.

A simple colour-coded scale on the rear indicates the relative danger level. Green or fewer than 12 bleeps per minute (bpm) is safe and represents normal background levels. Yellow or between 12 and 24 bpm and this indicates caution. Red is for 24 to 60 bpm and warns of a potential hazard and any more means danger, get out of there!

These ingenious little devices are relics of the post Chernobyl era and are no longer being made. They are now in extremely short supply and when they have gone there will be no more! The few units we have for sale were made over 10 years ago but they have been kept in storage and have never been used so they are in as-new condition and fully working. In fact the only signs of aging are the very slightly tatty cardboard storage boxes, otherwise they look as though they have just come out of the factory.

They are powered by two small button cells and they come with a pair of new re-chargeable cells and a mains charger. These cells will keep the BIRI-1 running continuously for 50 hours or more between charges.


However, in our opinion the charger units are a little crude. Whilst not electrically unsafe, they are fitted with an integral continental 2-pin plug, which will fit into a 2-pin shaver socket but requires an adaptor to be used on a standard 3-pin UK mains socket. Nevertheless, we advise against the use of the charger facility and suggest instead that you use readily available single-use button cell. Two will be supplied with each unit. On average these will run the unit non-stop for 4 - 5 days, or several weeks or even months with intermittent use. We can supply larger quantities of these cells at competitive prices if required. Dimensions 70 x 40 x 18mm. Weight (ex batteries) 50g.

My Review: EXCELLENT! Although it is not a dosimeter (it only measures rate), this is an excellent Geiger Counter. It is very sensitive, seems to be built pretty strongly, and has both loud audio and video output. I love mine - at this price, it is a giveaway! Best packaging ever, bubble-wrapped to the max.

This unit measures background counts of 30 CPM, just like my Geiger counters that cost over 10 TIMES as much.

tethered satellite observation? Double Sat - military spy?

HELP!! Please help identify this satellite event!

Seen from here:
http://www-2.net/y23.stock.pictures/200102_ngauruhoe_2/
Tongariro, New Zealand
on 07feb2009 22h12 (gmt+13) two satellites, flying as a pair, about one small
finger on stretched arm apart, almost vertical (7 and 1 o'clock) ... , through southern cross, direction left -- arching downwards .. gone behind trees after 5 minutes or so. Very faint, maybe 5th to 8th magnitude.

my USENET discussion was not very inormative...
http://groups.google.com/group/sci.astro.amateur/browse_thread/thread/0c41df79ebd981e5


There are two and three satellite constellations up there. I don't know of any that are tethered, however. Most likely you saw an untethered pair, probably spy satellites, or some sort of radar mapping system.

It sounds like there are currently no tethered satellites in orbit. I remember the TSS experiment, when the tether broke. That was a very interesting looking object from the ground.

Sounds like the NOSS thingies. That is I believe it what they are
called. The first time I saw them, I was simply amazed. There were
three of them, very faint and moving in perfect formation across the
night sky. I have seen them a couple of other times over the past

NZ SPYING SCANDAL - reuqest your file!

Can the SIS get any worse? First we learn about their decades-long surveillance of a peaceful activist group, now it turns out they were spying on Green MP Keith Locke, not just when he was an activist, but after he had been elected to parliament. They spied on his travel, they spied on his meetings with his constituents, and they monitored his activities in the House. Particularly, it seems, when they might affect the SIS:

The file includes clippings about his activities as an MP, including the official Hansard report of his speech in parliament proposing a bill to increase oversight of the SIS.
Because obviously, anyone who wants to stop the spies from undermining our democracy is clearly a threat to "national security".

Again, this is clear evidence that the SIS has gone too far. Rather than defending our democracy as they proclaim, they are in fact the greatest domestic threat to it. It's time we ended that threat, either by disbanding the whole organisation, or paring it back to a rump sufficient to its task (which in peaceful NZ, is probably about ten people). There is simply no place in a democracy for an organisation like the SIS, which spies on people solely on the basis of their political views.

Maire tackles the SIS for breakfast

PACIFIC peace campaigner Maire Leadbeater, author of the groundbreaking book Negligent Neighbour about New Zealand's shameful role over the Indonesian occupation of East Timor, was featured on TVNZ's chatty Breakfast show today. But behind all the light-hearted banter about a bygone era of paranoia, there are still sinister overtones for both NZ and the Asia-Pacific region. Maire was spied on by NZ's Security Intelligence Service (SIS) since the age of 10.
In a relatively new era of "transparency", security files have been handed over on request to a group of "activists and agitators". The move, as The Press noted in an editorial, recalls "a whiff of the musty battles of the cold war". After her Breakfast cameo, when she waved her hefty spook file that must have cost the taxpayers pointless zillions, Maire told Café Pacific:

While it's good that the SIS issue is being debated, the issue is more serious than just about the bad old cold war - "reds under the bed" - days. My file, in common with others, illustrates some quite intensive spying - "sources" planted in meetings, stake outs of conferences and so on.
But there is good reason to believe this undemocratic, wasteful activity is still continuing for some groups and individuals. It's possible that with the establishment of the new police Special Intelligence Branch the respective roles of police and SIS have changed a little.

Looking further afield in the Asia-Pacific region, she says:

Anti-communism is still strong in Indonesia, where the spreading of ideas and writing about Marxism-Leninism has been banned since 1967. The dictator Suharto rose to power by dint of a pogrom that wiped out at least half a million people deemed to be communists. Books are still banned if if they are deemed to be supportive of the PKI - the former Indonesian Communist Party - or if they give a "wrong" analysis of the events of 1 October 1965 and the murder of six army generals which triggered the bloodbath.
Indonesia's Criminal Code contains broad articles giving the authorities license to charge people that they consider to be subversive. For one human rights lawyer in West Papua that meant detention for 15 months and a trial for nothing more than forwarding a text message which alleged that the Indonesian Government was planning to cause harm to West Papuans. Fortunately he has just been acquitted. Those who dare to raise the banned
Morning Star flag or even depict its design on a bag or clothing run the real risk of going to jail.
West Papuans say that in the towns are villagers "intel" are always lurking and listening.
West Papuans say to us "please use your liberty to protect ours". So I guess that is one good reason why we also need to be vigilant about our own freedoms and right to meet and discuss ideas without being spied on!

CAFCA's secretary Murray Horton - another leading activist who obtained his organisation's SIS files (and then fired off a personal request while a Press reporter was at his office to interview him) - believes New Zealand's security service has behaved in some respects much the same way as communist police states.

Meanwhile,
in other fallout from the SIS papers issue, Helen Sutch, daughter of the late leading public intellectual and civil servant Dr Bill Sutch who was at the heart of NZ's most controversial "spy" case, has condemned The Press in a letter of peddling an "urban myth" about her father. Dr Sutch was wrongly accused by the SIS in 1974 of trying to pass off NZ government information to the Soviet Union. In the high profile case that followed, he was acquitted. Helen Sutch wrote:

The Press continues to besmirch Bill Sutch
I am disappointed that The Press continues to purvey an urban myth regarding Dr W.B. Sutch. This myth, that ''the SIS caught William Ball Sutch passing material to the Soviet Union'' (editorial, Jan 29), was shown at his trial in 1975 to be false, and no evidence has emerged
since then to undermine that finding.
While editorials contain opinion, they should not misrepresent it as based on fact when it is not. Instead, please take note of the following easily verifiable facts:
  • Dr Sutch was acquitted. The SIS did not ''catch him passing material to the Soviet Union''. The transcript of Dr Sutch's trial, which has always been a public document, shows this clearly.
  • The subsequent enquiry by the then Ombudsman, Sir Guy Powles, found that the SIS had broken the law and that Dr Sutch had not.
  • Disquiet at the arbitrary and oppressive nature of the Official Secrets Act, under which Dr Sutch had been charged, and to which Sir Guy and others drew attention, led to its repeal
  • and replacement by the Official Information Act.
If The Press had been interested in the real historical significance of the release of SIS files, it could have highlighted two important developments in the years since 1975.
First is the movement away from a secret, closed bureaucratic world towards a more transparent society in which the presumption under the OIA is that all information should be
publicly available unless strong arguments to the contrary can be made.
The second development relates to the recognition that the SIS needed to be made more accountable.
Greater governance safeguards are now in place aimed at preventing the abuses of power that New Zealand has suffered in the past.
While Wolfgang Rosenberg, to whom your editorial also casually referred, may have kept his job, his career may well have been damaged, and there are many others, such as the distinguished lawyer Dick Collins, who were prevented from following their chosen careers at all.

The CAFCA File: SIS spying on protest group for 25 years

The Campaign Against Foreign Control of Aotearoa (CAFCA) has recently been given 400 documents (documents, not pages) spanning from the 1970s to the late 90s, by Security Intelligence Service (SIS) Director, Dr Warren Tucker.
According to Murray Horton, the secretary of CAFCA, the SIS file includes:
  • Extremely detailed reports from meetings held in private homes. Mostly these are meeting of third party groups at which CAFCA itself or its members (such as me) were discussed. Obviously the SIS had a spy or spies in those other groups.
  • Reports from year after year of CAFCA Annual General Meetings and various public meetings we organised, including making “covert” calls to one of our speakers to check out who he was and to get him to inadvertently report on the meeting for the SIS. I should stress that these were meetings on subjects like West Coast coal exports and other innocuous topics.
  • Copious analyses of articles on all manner of topics in our newsletter Foreign Control Watchdog. This went on for years.
  • Intercepted private letters.
  • In the case of myself, evidence of dealings between my former employer (the Railways) and the SIS. One report included me on a “troublemakers in the union” list and included evidence of my employer asking the SIS for any evidence that I was connected to the then Socialist Unity Party (I never was, nor any other party). Also reports of my international travels in those years.
  • SIS conclusions that CAFCA was involved in historic “terrorist” acts (we weren’t) and endless speculation as to whether we (collectively and/or individually) were “Communists” (we weren’t).
  • CAFCA was the subject of reports of various SIS Directors to various Prime Ministers.
  • CAFCA was the subject of SIS correspondence with foreign intelligence agencies. CAFCA now has received the material that the SIS sent to foreign intelligence agencies, namely 10 1970s' vintage memos sent to the CIA at the US Embassy. The accompanying letter from Warren Tucker says that they date from the "anti-nuclear ship visit period of (your) history".
  • All details identifying SIS agents or informers have been removed.
Murray Horton says that group has not released this "treasure trove" because "either through sheer naivete or malice, the CAFCA File includes extremely indiscreet and personally damaging material about named third parties, people who were not the subject of the surveillance but simply caught up in its net. A lot of it is salacious gossip, with analyses of named people’s marriage problems, drinking habits, etc, etc. Some of it is laughable – e.g. there is a report dedicated to the likely impact of feminism and different gender views on abortion on the marriages of named couples. There are also gratuitously insulting references to CAFCA leaders such as myself - “he likes the sound of his own voice and keeps interrupting the other speakers”, which we would expect from somebody sent to spy on us."

However, Horton thinks the CAFCA File is only the tip of the iceberg. "Many individual members (not including me, yet) have received their own SIS Personal Files. For example, my colleague Bill Rosenberg has received not only his one but those of both his late parents (which, in the case of his father, Wolfgang Rosenberg, went back to the 1940s). We are aware of at least one sitting MP who has received his/her SIS Personal File, as has one current senior union official. Viewed collectively, these SIS files (the CAFCA one and the personal ones) reveal a fascinating and disturbing pattern of systematic covert State surveillance of many, many organisations (the Philippines Solidarity Network being one example of another group with which I’m involved) and many hundreds, if not thousands, of people over decades. And all in complete breach of the SIS Act which expressly forbids the SIS from spying on legal protest groups."

http://www.2p-spyphone.com/images/WhatareyouwearingTEXT383.jpg

"All of those SIS Personal Files also include the same gratuitous, personally damaging references to third parties who are not the subjects of the report but have just got swept up into it. It is up to the individuals as to whether they wish to make their SIS Personal Files available to the media."

"We believe that the NZ public and media deserve to have an unprecedented look at the secret work of our spies, to be able to evaluate the calibre of their “intelligence”, and for the public to see what is it that the SIS spends our taxes on. This is not really the stuff of newsbites; for a serious investigative journo, there’s a good long article in it." says Horton.

Apparently SIS Director Tucker confirmed to Murray Horton in writing that the spying on CAFCA has stopped. But he asks: "Where is the democracy if the powers that be exhibit an obsessive compulsion to spy on, and monitor all aspects of the lives of, legal political activists, ordinary citizens exercising their democratic rights?"


What 'intelligence' organisations such as the (SIS) or the Special Investigation Group (SIG) hate the most is publicity about their own activities. To the frustration of New Zealand's spies, their work - and their outrageous mess-ups - seem to get splattered across the country's major newspapers and broadcasted all over the 6pm news every other month. After Rob Gilchrist was outed as a paid informant for the SIG and Threat Assessment Unit (TAU) for around 10 years in December 2008, it is now the SIS' turn.

Several activists and groups, including the Campaign Against Foreign Control of Aotearoa, Marie Leadbeater (Indonesia Human Rights Committee), Keith Locke (Green Party MP and former member of Socialist Action League), Tim Shadbolt (now Mayor of Invercargill) and others have recently received their SIS file. What they found is quite astonishing.

Maire Leadbeater

Maire Leadbeater (63) is a long-time activist on peace issues. She was an early SIS target because of her Christchurch parents, Elsie and Jack Locke, who were prominent members of the New Zealand Communist Party and community activists. Elsie Locke left the Communist Party in 1956 when the Soviet Union invaded Hungary, but her husband stayed.

Leadbeater's file, which she received late last year, begins when she was 10, with a note that she delivered the Communist Party newspaper, the People's Voice, to the mother of twins in Bangor St, in central Christchurch.

The next item refers to her membership of a junior drama group that the file says was connected with the William Morris (a Fabian socialist) Group, regarded by the SIS as a front for the Communist Party. Elsie Locke performed in the group.

The file continues to track Leadbeater's life, although the SIS lost track of her when she married and took her husband's name. "They lost me for about 13 years," she said. Her file, like most of the others released, contains material from private meetings. "I find that the hardest to accept," Leadbeater said. "That small groups of people gathering together in private homes and offices should have someone planted in the meetings. It's pretty shocking really. It's potentially very bad for democracy because it makes people anxious about involving themselves in free discussion of ideas and has a big impact on trust if you have to think to yourself `one of us could be a source'."

She was surprised to find her file contains a list of every member of the Palestine Human Rights Committee. Her file contained references to the state of her parents' marriage, which the SIS thought would be strained by Elsie's departure from the party. "It's all wrong anyway," Leadbeater said. "It's unpleasant, inaccurate speculation about highly personal family issues."

The most recent item on her file is a reference to a member of the South Auckland Muslim Association who said she would be taking part in a march on September 28, 2002 Leadbeater's activities on behalf of the Fiji Coalition for Democracy, the anti-bases campaigns and the Ahmed Zaoui campaign are not mentioned in the file. "Does this mean that snooping is less or done in a different way?" she said.

Keith Locke

One of Leadbeater's siblings is Green MP Keith Locke, a former Trotskyist and member of the Socialist Action League who has also received his SIS file. He confirmed he had received his own file, which was thick, and his mother's biographer was in possession of his mother's file. He had yet to view his file and was not prepared to comment.

Tim Shadbolt

Invercargill Mayor Tim Shadbolt, who was once prominent in a number of radical movements, said he would be travelling to Wellington to uplift his file as part of a TV3 news programme. He was not sure the SIS kept a file on him, but said he would feel a bit insulted if it did not.

"It will make interesting reading. I suspect they would have got a lot more detail if they had just read my book Bullshit and Jellybeans," he said. Shadbolt said he had led at least five radical organisations, including the Radical Students Association and Auckland University Students for the Prevention of Cruelty to Politically Apathetic Humans. "If they figured out what [the latter organisation] was about, then good luck to them because we never could," he said.

Murray Horton

In November, Murray Horton, a former railway worker, applied for the file on the Campaign Against Foreign Control of Aotearoa (Cafca), an organisation he helped found. He received 400 documents, including a cover letter from SIS head Dr Wayne Tucker. It said the spying had stopped. The file presented a "fascinating and disturbing pattern of systematic covert state surveillance of many, many organisations and many hundreds, if not thousands, of people over decades", Horton said.

The identity of agents and sources of information was deleted from the files, said an SIS spokesman said. So much for democracy, Horton said. "Our own little country has been proven to behave towards its dissidents in much the same way as the Communist police states that it used to rail against," he said.

The worst of it was that the Cafca file and others released indiscreet and personally damaging material about named third parties who were not the subject of the surveillance but simply caught up in its net, he said. "A lot of it is salacious gossip, with analyses of named people's marriage problems, drinking habits, etc, etc," Horton said.

"Some of it is laughable, like a report dedicated to the likely impact of feminism and different gender views on abortion on the marriages of named couples." One report contained this reference to Horton: "He likes the sound of his own voice and keeps interrupting the other speakers."

A threat to democracy

In 2003, the SIS adopted a new archives policy which saw material declassified and able to be released to the public for the first time. Since then, various people have taken the opportunity to gain copies of their records. And the results have revealed just how much of a threat to democracy the SIS is. A piece in the Dominion-Post today reveals details of their spying on CAFCA - the Campaign Against Foreign Control of Aotearoa. CAFCA is a classic lobby group, issuing press releases, submitting to Parliament, organising petitions, promoting or opposing legislation, and issuing an annual "Roger Award" to highlight its cause. This is perfectly normal political activity in a democracy, and you would have to be absolutely demented to regard them as a "threat to security". So naturally the SIS spied on them for over a decade, invading the privacy of hundreds of people while doing so. And what did they find? The usual garbage:

"A lot of it is salacious gossip, with analyses of named people's marriage problems, drinking habits, etc, etc," Horton said.

"Some of it is laughable, like a report dedicated to the likely impact of feminism and different gender views on abortion on the marriages of named couples."

One report contained this reference to Horton: "He likes the sound of his own voice and keeps interrupting the other speakers."

Quelle horreur! Clearly a dangerous threat to national security!

Like the police SIG, this speaks of an organisation with not enough real work to do, which has turned its sights on ordinary political activists in order to justify its budget. By doing so, they have shown themselves to be a far greater threat to democracy than their imaginary "subversives". The scary thing is that their budget has tripled in recent years due to the "war on terror", but there is still nothing for them to do. There are no real terrorists in New Zealand, just as there were no Russian agents. Which raises the question: who are they spying on now?

The past history of the SIS shows that rather than protecting New Zealand's democracy, it has worked systematically to undermine it. That is not acceptable. The organisation should either be disbanded, or gutted back to a rump sufficient to its task (which is probably less than ten people). Either way, our democracy will be safer for it.



Chapter Two:
Hooked up to the spy network:
The UKUSA system

Ten years later, on Saturday, 15 January 1994, technicians in satellite earth stations around the Pacific were busy tuning their equipment to a new satellite. The first of the new generation of Intelsat 7 series satellites, it had been launched several weeks before, from the European Kourou air base in French Guyana, and then manoeuvred into position far out in space above the Equator at 174 degrees east, due north of New Zealand above Kiribati.

The 20 Intelsat (International Telecommunications Satellite Organisation) satellites that ring the world above the Equator carry most of the world's satellite-relayed international phone calls and messages such as faxes, e-mail and telexes. The new satellite, Intelsat 701, replaced the 10-year-old Intelsat 510 in the same position. The changeover occurred at 10 pm New Zealand time that summer evening.

At the GCSB's station at Waihopai, near Blenheim in the north of the South Island, the radio officer staff were just as busy that evening, setting their special equipment to intercept the communications which the technicians in legitimate satellite earth stations would send and receive via the new satellite. These specially trained radio officers, who learned their skills at the Tangimoana station, usually work day shifts, but on 15 January 1994 they worked around the clock, tuning the station's receivers to the frequency bands the GCSB wanted to intercept, selecting the specific channels within each band that would yield the types of messages sought within the UKUSA network and then testing that the high-tech intelligence collection system was working smoothly. That satellite changeover was a very significant event for the Waihopai station and the GCSB. Although it would always be only a small component of the global network, this was the moment when the station came into its own.

There have been various guesses and hints over the years about what the Waihopai station was set up to monitor -- "sources" in one newspaper said foreign warship movements; a "senior Telecom executive" told another newspaper it was most likely "other countries" military communications" -- but, outside a small group of intelligence staff, no one could do more than theorise. Waihopai was established specifically to target the international satellite traffic carried by Intelsat satellites in the Pacific region and its target in the mid-1990s is the Intelsat 701 that came into service in January 1994, and is the primary satellite for the Pacific region.

Intelsat satellites carry most of the satellite traffic of interest to intelligence organisations in the South Pacific: diplomatic communications between embassies and their home capitals, all manner of government and military communications, a wide range of business communications, communications of international organisations and political organisations and the personal communications of people living throughout the Pacific. The Intelsat 7 satellites can carry an immense number of communications simultaneously. Where the previous Intelsat 5s could carry 12,000 individual phone or fax circuits at once, the Intelsat 7s can carry 90,000. All "written" messages are currently exploited by the GCSB. The other UKUSA agencies monitor phone calls as well.

The key to interception of satellite communications is powerful computers that search through these masses of messages for ones of interest. The intercept stations take in millions of messages intended for the legitimate earth stations served by the satellite and then use computers to search for pre-programmed addresses and keywords. In this way they select out manageable numbers (hundreds or thousands) of messages to be searched through and read by intelligence analysis staff.

Until the Intelsat 701 satellite replaced the older 5 series, all the communications intercepted at Waihopai could already be got from two existing UKUSA stations covering the Pacific. But, unlike their predecessors, this new generation of Intelsat 7s had more precise beams transmitting communications down to the southern hemisphere. The existing northern hemisphere-based stations were no longer able to pick up all the southern communications, which is why new stations were required.

Eleven months later, on 3 December 1994, the other old Intelsat satellite above the Pacific was replaced by Intelsat 703. Since then Waihopai and its sister station in Australia constructed at the same time have been the main source of southern hemisphere Pacific satellite communications for the UKUSA network.

Many people are vaguely aware that a lot of spying occurs, maybe even on them, but how do we judge if it is ubiquitous or not a worry at all? Is someone listening every time we pick up the telephone? Are all our Internet or fax messages being pored over continuously by shadowy figures somewhere in a windowless building? There is almost never any solid information with which to judge what is realistic concern and what is silly paranoia.

What follows explains as precisely as possible -- and for the first time in public -- how the worldwide system works, just how immense and powerful it is and what it can and cannot do. The electronic spies are not ubiquitous, but the paranoia is not unfounded.

The global system has a highly secret codename -- ECHELON. It is by far the most significant system of which the GCSB is a part, and many of the GCSB's daily operations are based around it. The intelligence agencies will be shocked to see it named and described for the first time in print. Each station in the ECHELON network has computers that automatically search through the millions of intercepted messages for ones containing pre-programmed keywords or fax, telex and e-mail addresses. For the frequencies and channels selected at a station, every word of every message is automatically searched (they do not need your specific telephone number or Internet address on the list).

All the different computers in the network are known, within the UKUSA agencies, as the ECHELON Dictionaries. Computers that can search for keywords have existed since at least the 1970s, but the ECHELON system has been designed to interconnect all these computers and allow the stations to function as components of an integrated whole. Before this, the UKUSA allies did intelligence collection operations for each other, but each agency usually processed and analysed the intercept from its own stations. Mostly, finished reports rather than raw intercept were exchanged.

Under the ECHELON system, a particular station's Dictionary computer contains not only its parent agency's chosen keywords, but also a list for each of the other four agencies. For example, the Waihopai computer has separate search lists for the NSA, GCHQ, DSD and CSE in addition to its own. So each station collects all the telephone calls, faxes, telexes, Internet messages and other electronic communications that its computers have been pre-programmed to select for all the allies and automatically sends this intelligence to them. This means that the New Zealand stations are used by the overseas agencies for their automatic collecting -- while New Zealand does not even know what is being intercepted from the New Zealand sites for the allies. In return, New Zealand gets tightly controlled access to a few parts of the system.

When analysts at the agency headquarters in Washington, Ottawa, Cheltenham and Canberra look through the mass of intercepted satellite communications produced by this system, it is only in the technical data recorded at the top of each intercept that they can see whether it was intercepted at Waihopai or at one of the other stations in the network. Likewise, GCSB staff talk of the other agencies' stations merely as the various "satellite links" into the integrated system. The GCSB computers, the stations, the headquarters operations and, indeed, the GCSB itself function almost entirely as components of this integrated system.

In addition to satellite communications, the ECHELON system covers a range of other interception activities, described later. All these operations involve collection of communications intelligence,<> as opposed to other types of signals intelligence such as electronic intelligence, which is about the technical characteristics of other countries' radar and weapon systems.

Interception of international satellite communications began in the early 1970s, only a few years after the first civilian communications satellites were launched. At this time the Intelsat satellites, located over the Atlantic, Pacific and Indian Oceans, simply beamed all their messages down to the entire hemisphere within their view.

Throughout the 1970s only two stations were required to monitor all the Intelsat communications in the world: a GCHQ station in the south-west of England had two dishes, one each for the Atlantic and Indian Ocean Intelsats, and an NSA station in the western United States had a single dish covering the Pacific Intelsat.

The English station is at Morwenstow, at the edge of high cliffs above the sea at Sharpnose Point in Cornwall. Opened in 1972-73, shortly after the introduction of new Intelsat 4 satellites, the Morwenstow station was a joint British-American venture, set up using United States-supplied computers and communications equipment, and was located only 110 kilometres from the legitimate British Telecom satellite station at Goonhilly to the south. In the 1970s the Goonhilly dishes were inclined identically towards the same Atlantic and Indian Ocean satellites.<>

The Pacific Intelsat satellite was targeted by an NSA station built on a high basalt tableland inside the 100,000-hectare United States Army Yakima Firing Centre, in Washington State in the north-west United States, 200 kilometres south-west of Seattle. Also established in the early 1970s, the Yakima Research Station initially consisted of a long operations building and the single large dish. In 1982, a visiting journalist noted that the dish was pointing west, out above the Pacific to the third of the three Intelsat positions.<>

Yakima is located between the Saddle Mountains and Rattlesnake Hills, in a desert of canyons, dunes and sheer rock cliffs, where the only vegetation is grass. The Army leases the land to ranchers who herd their cattle in the shadow of the dishes. When visited in mid-1995 the Yakima station had five dish antennae, three facing westwards over the Pacific Ocean and two, including the original large 1970s dish, facing eastwards. Besides the original operations building there were several newer buildings, the largest of them two-storey, concrete and windowless.

Two of the west-facing dishes are targeted on the main Pacific Intelsat satellites; the Yakima station has been monitoring Pacific Intelsat communications for the NSA ever since it opened. The orientation of the two east-facing dishes suggests that they may be targeted on the Atlantic Intelsats, intercepting communications relayed towards North and South America. One or both may provide the link between the station and the NSA headquarters in Washington. The fifth dish at the station is smaller than the rest and faces to the west. Given its size and orientation, it appears to be the UKUSA site for monitoring the Inmarsat-2 satellite that provides mobile satellite communications in the Pacific Ocean area. If so, this is the station that would, for example, have been monitoring Greenpeace communications during the nuclear testing protests in the waters around Moruroa Atoll in 1995.

The GCSB has had important links with the Yakima station since 1981, when the GCSB took over a special, highly secret area of intelligence analysis for the UKUSA network (see Chapter 6). Telexes intercepted using Yakima's single dish were first sorted by the Yakima computers, and then subjects allocated to New Zealand were sent to the GCSB for analysis. The Yakima station had been using Dictionary-type computers for this searching work for many years before the full ECHELON system was operating.

Between them, the Morwenstow and Yakima stations covered all Intelsat interception during the 1970s. But a new generation of Intelsat satellites launched from the late 1970s required a new configuration of spy stations. The Intelsat 4A and 5 series satellites differed from earlier ones in that they did not transmit only to the whole of the side of the world within their view; they now also had "east and west hemispheric" beams that transmitted separately.<> For example, Intelsat 510, which operated above the Pacific until its replacement in December 1994, had one "global" beam covering the whole region, but all the other transmissions went either to the east or to the west Pacific. Yakima was not within the "footprint" of any hemispheric beams covering Australasia, South East Asia and East Asia, making interception of these signals difficult or impossible.

These changes to Intelsat design meant that the UKUSA alliance required at least two new stations to maintain its global coverage. Again the GCHQ provided one and the NSA one. A new NSA station on the east coast of the United States would cover Atlantic Intelsat traffic beamed down towards North and South America (Morwenstow covered the eastern Atlantic), and a GCHQ station in Hong Kong would cover both the western hemisphere of the Pacific Intelsats and the eastern hemisphere of the Indian Ocean Intelsats.

The site chosen for the new NSA station was hidden in the forested South Fork Valley in the mountains of West Virginia, about 250 kilometres south-west from Washington DC, on the edge of the George Washington National Forest, near the small settlement of Sugar Grove. The site had been used in the 1950s and early 1960s for a failed attempt to spy on Russian radio communications and radars by means of reflections from the moon. The current satellite interception station was developed during the late 1970s, when a collection of new satellite dishes (from 10 to 45 metres in diameter) and the new windowless Raymond E. Linn Operations Building were constructed. It also incorporated a two-storey underground operations building already at the site. It started full operations about 1980.<>

Like Morwenstow and Yakima, Sugar Grove is only 100 kilometres from an international satellite communications earth station, making it easy to intercept any "spot" beams directed down to the legitimate stations. In this case it is the Etam earth station, the main link in the United States with the Intelsat satellites above the Atlantic Ocean.

The other new station, in Hong Kong, was constructed by the GCHQ also in the late 1970s. The station, which has since been dismantled, was perched above the sea on the south side of Hong Kong Island, across Stanley Bay from the British Stanley Fort military base and right next to high-rise apartments and luxury housing. In crowded Hong Kong the station's anonymity was assured simply because there are so many satellite dishes scattered over the island. What helped to give away this one was the sign, on the entrance to an exclusive housing enclave across the bay, saying that taking photographs is strictly forbidden. When one of the Indian guards on the gate was asked why it was forbidden to take photos of a housing area, he pointed across the bay and said in serious tones, "Communications facility -- very, very secret".

The Hong Kong station had several satellite dishes and buildings, including a large windowless concrete building (similar to the ones at Yakima and Sugar Grove) and a collection of administration and operations buildings running down the hill into the base from the gates. Intelsat communications intercepted at the station were seen regularly by GCSB operations staff in Wellington.<>

When visited in August 1994, the station fitted the requirements of the Intelsat monitoring network. It had one dish pointing up east towards the Pacific Intelsats, another towards the Indian Ocean Intelsats and a third, for the station's own communications, pointing up to a United States Defence Satellite Communications System satellite above the Pacific. Other dishes had perhaps already been removed. Dismantling of the station began in 1994 -- to ensure it was removed well before the 1997 changeover to Chinese control of Hong Kong -- and the station's staff left in November that year. News reports said that the antennae and equipment were being shipped to the DSD-run Shoal Bay station in Northern Australia, where they would be used for intercepting Chinese communications.

It is not known how the Hong Kong station has been replaced in the global network. One of the Australian DSD stations -- either Geraldton or Shoal Bay -- may have taken over some of its work, or it is possible that another north-east Asian UKUSA station moved into the role. For example, there were developments at the NSA's Misawa station in northern Japan in the 1980s that would fit well with the need for expanded Intelsat monitoring.<>

Throughout the 1980s a series of new dishes was also installed at the Morwenstow station, to keep up with expansion of the Intelsat network. In 1980 it still required only the two original dishes, but by the early 1990s it had nine satellite dishes: two inclined towards the two main Indian Ocean Intelsats, three towards Atlantic Ocean Intelsats, three towards positions above Europe or the Middle East and one dish covered by a radome.

The Morwenstow, Yakima, Sugar Grove and Hong Kong stations were able to provide worldwide interception of the international communications carried by Intelsat throughout the 1980s. The arrangement within the UKUSA alliance was that, while the NSA and GCHQ ran the four stations, each of the five allies (including the GCSB) had responsibility for analysing some particular types of the traffic intercepted at these stations.

Then, in the late 1980s, another phase of development occurred. It may have been prompted by approaching closure of the Hong Kong station, but a more likely explanation is that, as we have seen, technological advances in the target Intelsat satellites again required expansion of the network.

Two UKUSA countries were available to provide southern hemisphere coverage: Australia and New Zealand. One of the new southern hemisphere stations would be the GCSB's Waihopai station and the other would be at Geraldton in West Australia. (Both stations are described in detail later.) The new stations were operating by 1994 when the new Intelsat 7s began to be introduced. Waihopai had opened in 1989, with a single dish, initially covering one of the older generation of Intelsat satellites.

The positioning of the Geraldton station on Australia's extreme west coast was clearly to allow it to cover the Indian Ocean Intelsats (they all lie within 60 degrees of the station, which allows good reception). Geraldton opened in 1993, with four dishes, covering the two main Indian Ocean Intelsats (at 60 degrees and 63 degrees) and possibly a new Asia-Pacific Intelsat introduced in 1992. It also covers the second of the two Pacific Intelsats, Intelsat 703.

The logic of the system suggests that, at the same time as the Waihopai and Geraldton stations were added to the network, a seventh, as yet undiscovered, station may have been installed in the South Atlantic. This station, probably located on Ascension Island, would complete the 1990s network by intercepting the Atlantic Intelsats' southern hemisphere communications.<>

New GCSB operations staff attend training sessions that cover the ECHELON system, showing how the GCSB fits into the system and including maps showing the network of UKUSA stations around the world. The sessions include briefings on the Intelsat and the maritime Inmarsat satellites -- their locations, how they work, what kinds of communications they carry and the technical aspects of their vulnerability to spying. This is because these are primary targets for the UKUSA alliance in the Pacific.

But the interception of communications relayed by Intelsat and Inmarsat is only one component of the global spying network co-ordinated by the ECHELON system. Other elements include: radio listening posts, including the GCSB's Tangimoana station; interception stations targeted on other types of communications satellites; overhead signals intelligence collectors (spy satellites) like those controlled from the Pine Gap facility in Australia; and secret facilities that tap directly into land-based telecommunications networks.

What Waihopai, Morwenstow and the other stations do for satellite communications, another whole network of intercept stations like Tangimoana, developed since the 1940s, does for radio.

There are several dozen radio interception stations run by the UKUSA allies and located throughout the world. Many developed in the early years of the Cold War and, before satellite communications became widespread in the 1980s, were the main ground signals intelligence stations targeting Soviet communications. Some stations were also used against regional targets. In the Pacific, for example, ones with New Zealand staff were used to target groups and governments opposed by Britain and the United States through a series of conflicts and wars in South East Asia.

A recent new radio interception station is the Australian DSD station near Bamaga in northern Queensland, at the tip of Cape York. It was set up in 1988 particularly to monitor radio communications associated with the conflict between Papua New Guinea and the secessionist movement in Bougainville.<> GCSB staff are also aware of Australian intercept staff posted in the early 1990s to the recently opened Tindal Air Force base in northern Australia, suggesting that an even newer -- as yet undisclosed -- DSD intercept station may have been established there.

Most of this network of stations target long-range high frequency (HF) radio. A powerful HF radio transmitter can transmit right around the world, which is why HF radio has been a major means of international communications and is still widely used by military forces and by ships and aircraft. Other stations target short-range communications -- very high frequency and ultra high frequency radio (VHF and UHF) -- which, among other things, are used extensively for tactical military communications within a country.

There is a wide variety of these radio interception operations. Some are very large, with hundreds of staff; others are small -- a few staff hidden inside a foreign embassy bristling with radio aerials on the roof; others (like the Bamaga station) are unstaffed, with the signals automatically relayed to other stations. Because of the peculiarities of radio waves, sometimes stations far from the target can pick up communications that closer ones cannot.

Each station in this network -- including the GCSB's Tangimoana station -- has a Dictionary computer like those in the satellite intercept stations. These search and select from the communications intercepted, in particular radio telexes, which are still widely used, and make these available to the UKUSA allies through the ECHELON system.

The UKUSA network of HF stations in the Pacific includes the GCSB's Tangimoana station (and before it one at Waiouru), five or more DSD stations in Australia, a CSE station in British Columbia, and NSA stations in Hawaii, Alaska, California, Japan, Guam, Kwajalein and the Philippines. The NSA is currently contracting its network of overseas HF stations as part of post-Cold War rationalisation. This contraction process includes, in Britain, the closure of the major Chicksands and Edzell stations.

The next component of the ECHELON system covers interception of a range of satellite communications not carried by Intelsat. In addition to the six or so UKUSA stations targeting Intelsat satellites, there are another five or more stations targeting Russian and other regional communications satellites. These stations are located in Britain, Australia, Canada, Germany and Japan. All of these stations are part of the ECHELON Dictionary system. It appears that the GCHQ's Morwenstow station, as well as monitoring Intelsat, also targets some regional communications satellites.

United States spy satellites, designed to intercept communications from orbit above the earth, are also likely to be connected into the ECHELON system. These satellites either move in orbits that criss-cross the earth or, like the Intelsats, sit above the Equator in geostationary orbit. They have antennae that can scoop up very large quantities of radio communications from the areas below.

The main ground stations for these satellites, where they feed back the information they have gathered into the global network, are Pine Gap, run by the CIA near Alice Springs in central Australia, and the NSA-directed Menwith Hill and Bad Aibling stations, in England and Germany respectively.<> These satellites can intercept microwave trunk lines and short-range communications such as military radios and walkie-talkies. Both of these transmit only line of sight and so, unlike HF radio, cannot be intercepted from faraway ground stations.

The final element of the ECHELON system are facilities that tap directly into land-based telecommunications systems, completing a near total coverage of the world's communications. Besides satellite and radio, the other main method of transmitting large quantities of public, business and government communications is a combination of undersea cables across the oceans and microwave networks over land. Heavy cables, laid across the seabed between countries, account for a large proportion of the world's international communications. After they emerge from the water and join land-based microwave networks, they are very vulnerable to interception.

The microwave networks are made up of chains of microwave towers relaying messages from hilltop to hilltop (always in line of sight) across the countryside. These networks shunt large quantities of communications across a country. Intercepting them gives access to international undersea communications (once they surface) and to international communication trunk lines across continents. They are also an obvious target for large-scale interception of domestic communications.

Because the facilities required to intercept radio and satellite communications -- large aerials and dishes -- are difficult to hide for too long, that network is reasonably well documented. But all that is required to intercept land-based communication networks is a building situated along the microwave route or a hidden cable running underground from the legitimate network. For this reason the worldwide network of facilities to intercept these communications is still mostly undocumented.

Microwave communications are intercepted in two ways: by ground stations, located near to and tapping into the microwave routes, and by satellites. Because of the curvature of the earth, a signals intelligence satellite out in space can even be directly in the line of a microwave transmission. Although it sounds technically very difficult, microwave interception from space by United States spy satellites does occur. <>

A 1994 expos of the Canadian UKUSA agency called Spyworld,<> co-authored by a previous staff member, Mike Frost, gave the first insights into how much microwave interception is done. It described UKUSA "embassy collection" operations, where sophisticated receivers and processors are secretly transported to their countries' overseas embassies in diplomatic bags and used to monitor all manner of communications in the foreign capitals.

Since most countries' microwave networks converge on the capital city, embassy buildings are an ideal site for microwave interception. Protected by diplomatic privilege, embassies allow the interception to occur from right within the target country.<> Frost said the operations particularly target microwave communications, but also other communications including car telephones and short-range radio transmissions.

According to Frost, Canadian embassy collection began in 1971 following pressure from the NSA. The NSA provided the equipment (on indefinite loan), trained the staff, told them what types of transmissions to look for on particular frequencies and at particular times of day and gave them a search list of NSA keywords. All the intelligence collected was sent to the NSA for analysis. The Canadian embassy collection was requested by the NSA to fill gaps in the United States and British embassy collection operations, which were still occurring in many capitals around the world when Frost left the CSE in 1990.

Separate sources in Australia have revealed that the DSD also engages in embassy collection. Leaks in the 1980s described installation of "extraordinarily sophisticated intercept equipment, known as Reprieve in Australia's High Commission in Port Moresby, Papua New Guinea and in the embassies in Indonesia and Thailand. The operations are said to take a whole room of the embassy buildings and to be able to listen to local telephone calls at will.<> There is good reason to assume that these operations, too, were prompted by and supported with equipment and technical advice from the NSA and GCHQ.

Of course, when the microwave route is across one of the UKUSA countries' territory it is much easier to arrange interception. For example, it is likely that there is a GCHQ operation intercepting, and feeding through Dictionary computers, all the trans-Atlantic undersea cable communications that come ashore in Cornwall.

There are also definitely United States and possibly Canadian facilities for this type of interception. By far the most important of these is the NSA-directed Menwith Hill station in Britain. With its 22 satellite terminals and over 2 hectares of buildings, Menwith Hill is undoubtedly the largest station in the UKUSA network. In 1992 some 1200 United States personnel were based there.<> British researcher Duncan Campbell has described how Menwith Hill taps directly into the British Telecom microwave network, which has actually been designed with several major microwave links converging on an isolated tower connected underground into the station.<> The station also intercepts satellite and radio communications and is a ground station for the electronic eavesdropping satellites. Each of Menwith Hill's powerful interception and processing systems presumably has its own Dictionary computers connected into the ECHELON system.

Menwith Hill, sitting in northern England, several thousand kilometres from the Persian Gulf, was awarded the NSA's Station of the Year prize for 1991 following its role in the Gulf War. It is a station which affects people throughout the world.

In the early 1980s James Bamford uncovered some information about a worldwide NSA computer system codenamed Platform which, he wrote, "will tie together fifty-two separate computer systems used throughout the world. Focal point, or Òhost environmentÓ, for the massive network will be the NSA headquarters at Fort Meade. Among those included in Platform will be the British SIGINT organisation, GCHQ. <>

There is little doubt that Platform is the system that links all the major UKUSA station computers in the ECHELON system. Because it involves computer-to-computer communications, the GCSB and perhaps DSD were only able to be integrated into the system in the 1990s when the intelligence and military organisations in the two countries changed over to new computer-based communications systems.

The worldwide developments, of which construction of the Waihopai station was part, were co-ordinated by the NSA as Project P415. Although most of the details remained hidden, the existence of this highly secret project targeting civilian communications was publicised in August 1988 in an article by Duncan Campbell. He described how the UKUSA countries were "soon to embark on a massive, billion-dollar expansion of their global electronic surveillance system', with "new stations and monitoring centres ... to be built around the world and a chain of new satellites launched'.

The satellite interception stations reported to be involved in P415 included the NSA's Menwith Hill station, the GCHQ's Morwenstow and Hong Kong stations and the Waihopai and Geraldton stations in the South Pacific. Other countries involved, presumably via the NSA, were said to be Japan, West Germany and, surprisingly, the People's Republic of China.

"Both new and existing surveillance systems are highly computerised," Campbell explained. "They rely on near total interception of international commercial and satellite communications in order to locate the telephone and other target messages of target individuals....<>

There were two components to the P415 development, the first being the new stations required to maintain worldwide interception. More striking, though, was the expansion of the NSA's ECHELON system, which now links all the Dictionary computers of all the participating countries.

The ECHELON system has created an awesome spying capacity for the United States, allowing it to monitor continuously most of the world's communications. It is an important component of its power and influence in the post-Cold War world order, and advances in computer processing technology continue to increase this capacity.

The NSA pushed for the creation of the system and has the supreme position within it. It has subsidised the allies by providing the sophisticated computer programmes used in the system, it undertakes the bulk of the interception operations and, in return, it can be assumed to have full access to all the allies' capabilities.

Since the ECHELON system was extended to cover New Zealand in the late 1980s, the GCSB's Waihopai and Tangimoana stations -- and indeed all the British, Canadian and Australian stations too -- can be seen as elements of a United States system and as serving that system. The GCSB stations provide some information for New Zealand government agencies, but the primary logic of these stations is as parts of the global network.

On 2 December 1987, when Prime Minister David Lange announced plans to build the Waihopai station, he issued a press statement explaining that the station would provide greater independence in intelligence matters: "For years there has been concern about our dependence on others for intelligence -- being hooked up to the network of others and all that implies. This government is committed to standing on its own two feet."

Lange believed the statement. Even as Prime Minister, no one had told him about the ECHELON Dictionary system and the way that the Waihopai station would fit into it. The government was not being told the truth by officials about New Zealand's most important intelligence facility and was not being told at all about ECHELON, New Zealand's most important tie into the United States intelligence system. The Waihopai station could hardly have been more "hooked up to the network of others", and to all that is implied by that connection.

It does not include foreign press, propaganda or public broadcasts." It generally refers to external intelligence and so does not usually include governments spying on their own people.

6. The station may not have been initially targeted on Intelsat. Some photos of the station taken by Des Ball in June 1983 show the two interception dishes facing directly skywards, meaning either that they were temporarily not being used or that they were targeted at that time on satellites above East Asia (in the early 1980s there were no Intelsats there).

7. A US$29 million project codenamed LADYLOVE at the station, for completion in mid-1982, involved an "interim deployment" construction of one dish and a "new operational electronic system" housed initially in equipment vans. A US$21 million "major new collection and processing complex with associated antenna systems" followed in 1987.

With apologies to North Korea because she shouldn’t be insulted by being compared with New Zealand!

NZ Dollar, ANZ Bank, Spies, Assassins, Phone Tapping, Attempted Murder and the Military Regime with a Civilian Face

In reply to a message by a NZ Journalist, TERRES

A colleague who lived in NZ and who has done some research on the “cloak and dagger” operations worldwide, believes a considerable number of “spies” [other than the obvious operatives from the US, UK, Canada and Australia] freely [with the full knowledge and consent of NZ govt.] operate in New Zealand. [He also informs me that he has inadvertently met a few of them in Nelson and in the Golden Bay area.] The operatives, he asserts, include Israeli, German, Italian, Danish … agents and former MI personnel from SA and Zimbabwe. [He has not disclosed the specific details.]

The worst culprits are by far New Zealand’s own “Canadian-trained” SS-like SIS agents [see links below,] my colleague contends, who occupy all the managerial and top positions within the government branches [e.g., NZ "Trade and Enterprise"] effectively transforming a civilian form of government into a “crypto-military fascist police state,” or an outright military regime with a civilian face like China or North Korea.
