Abstract
The radionuclide monitoring network enables continuous world-wide observation of airborne radionuclides in the verification regime of the Comprehensive Nuclear Test-Ban-Treaty (CTBT). The radionuclide technology – analysis of aerosol samples and xenon at 80 sites hosting radionuclide monitoring stations – contributes to the International Monitoring System (IMS). Sixteen radionuclide laboratories will support the radionuclide monitoring network. Their main function is additional analysis of aerosol samples. Samples categorised as Level 5 that contain multiple anthropogenic radionuclides, at least one of which is a fission or an activation product, will always be sent out for laboratory analysis. A number of samples will be re-analysed at the radionuclide laboratories irrespective of category. This serves the purpose of quality control for the results produced by the stations.
Abstract
Innerhalb des Überwachungssystems des Vertrages über das umfassende Verbot von Nuklearversuchen ermöglicht das Radionuklidnetzwerk eine ununterbrochenene weltweite Beobachtung der sich in der Luft befindlichen Radionuklide. Die Radionuklidtechnologie basiert auf der Analyse von Aerosolproben und Xenon an 80 Radionuklidstationen und trögt so zu dem Internationalen Überwachungssystem bei. Sechzehn Radionuklidlabors werden dieses Radionuklid-Überwachungssystem unterstützen. Die Hauptfunktion dieser Radionuklidlabors ist die Analyse von Aerosolproben. Proben, die als Stufe 5 kategorisiert werden und mehrere anthropogene Radionuklide beinhalten, von denen mindestens eines ein Spalt- oder Aktivierungsprodukt ist, werden immer zur Analyse in ein Labor geschickt. Viele Proben werden unabhängig von ihrer Kategorie zur nochmaligen Analyse in die Radionuklidlabors geschickt. Dieses geschieht zur Qualitätskontrolle der Ergebnisse der Stationen.
