Abstract

This article focuses on optimizing the performance of radioactivity monitoring systems using High Purity Germanium (HPGe) γ-spectrometry for atmospheric particulate samples during nuclear emergencies. It identifies key parameters affecting Minimum Detectable Activities (MDAs) of radionuclides in a "Chernobyl-like" radioactive cloud and proposes an optimized measurement protocol balancing sensitivity and response time. The study calculates MDAs achievable with a standard 30% efficiency HPGe detector and establishes that the best sensitivity is obtained by allocating two-thirds of the total measurement time to sampling and one-third to counting. The resulting system can detect radionuclide concentrations corresponding to an inhalation dose well below the 10 μSv threshold of radiological insignificance set by European regulations.
