International Monitoring System Data
"The United States operates particle and gas samplers to support the Comprehensive Test Ban Treaty Organization's International Monitoring System. The samplers are designed to collect and measure trace level radioisotopes that might be released into the atmosphere during an underground or atmospheric nuclear test. The reports on this page summarize the collection parameters and the radionuclides detected at the US samplers."
