Description
Atmospheric radionuclide monitoring with high-purity germanium (HPGe) detectors is a crucial component of verifying compliance with treaties that prohibit the use of nuclear weapons, such as the Comprehensive Nuclear-Test-Ban Treaty (CTBT). To improve detection sensitivity, coincidence gamma-ray spectrometers, which measure gamma rays emitted in a cascade, are being developed. The CoSpeR collaboration between Uppsala University and the Swedish Defence Research Agency (FOI) aims to optimize the minimum detectable activity of key radionuclides for coincidence gamma-ray spectrometers using simulations in Geant4. This talk will discuss the theory behind the detection technique, present progress in simulating detector performance, and outline the future course toward optimized detector designs.
