Abstract

Decommissioning of legacy nuclear facilities or clean up in the aftermath of a nuclear
incident requires detailed knowledge of the amount, type and distribution of nuclear materials
present. One technique available to rapidly provide this information in-situ is high-precision
gamma spectroscopy. These spectrometers rely on precision measurements of energy deposited in
the spectrometer crystal from incident photons. However, the high precision limits the speed of
the measurements and therefore limits the upper threshold of radiation levels that can be measured.
In this work we present results from a simulation design study of a novel, small and light-weight
multi-detector system with fast readout, that is suitable for isotope detection at high radiation levels.
