A consideration of radionuclide particulate resuspension as a verification tool in the CTBT On-Site Inspection verification component

A considerable amount of radioactivity could leak from an underground nuclear test at levels easily detectable by one or more of the radiological methods available for on-site inspection, even if the event does not immediately result in gas or particulate debris reaching stations of the International Monitoring System, of the Comprehensive Nuclear-Test-Ban Treaty. This work presents a feasibility study showing that winds or human activity can resuspend surface debris in quantities that could be detected using high-volume aerosol samplers outside an established restricted area and subsequent measurement in a Base of Operations laboratory.
