Radiochemistry Aims and scope

Abstract

The International Monitoring System enables continuous worldwide observation of airborneradionuclides for the Comprehensive Nuclear-Test-Ban Treaty by analyzing aerosol samples, xenonat 80 sites of a network of radionuclide stations. The design of the network aims at a 90% detection prob-ability for a nuclear explosion of 1 kt or above within ten days after the detonation. For aerosol stations the minimum detectable concentration (MDC) for 1 4 0Ba should be below 10-30 μBq m- 3, and the MDC for 1 3 3Xe at noble gas stations should be below 1 mBq m- 3. Stations send their data via a communications satellite to the International Data Centre in Vienna where the spectra are analyzed and categorized.
