Abstract

Hand-Held RadioIsotope Identification Devices (HHRIID) are defined as a new class of portable neutron/gamma radiation detectors with specifications presented in the ANSI Standards N42.33 and N42.34. We have proposed a novel HHRIID design concept which uses a single photosensor to detect light emitted by two optically separated scintillator materials, one optimized for gamma detection and the other optimized for neutron detection. This work describes the performance of a modified charge integration discrimination method developed to test the viability of the new design. The scintillators chosen for the experiment were LYSO and ZnS:Ag/LiF.
