New radiation hodoscope developments for arms control treaty verification

New developments in hodoscope radiation detection technology offer a wide range of unique capabilities for arms control treaty verification (ACTV) applications. Gamma-ray transmission hodoscopes can be used to inspect canisters, rail cars, etc., to monitor objects, such as rocket motors. Monitoring of rocket motors enclosed in canisters/rail cars is the focus of the most recent ACTV hodoscope research and development activities and is described. Rocket monitoring or discrimination, requires that the inspection determine that the size of a specific enclosed rocket motor is within agreed-upon limits. This requires limited intrusiveness. The measurements confirmed the applicability of a gamma-ray transmission hodoscope for monitoring the size of a rocket motor, enclosed within a structure.<
