Phoswich detectors for simultaneous counting of α-, β(γ)-rays and neutrons

Simultaneous counting of α-, β(including γ)-rays, fast and thermal neutrons was accomplished by devising phoswich detectors with pulse-shape discrimination. The detectors consisted of ZnS(Ag), anthracene and 6Li-glass (NS8) scintillators: ZnS(Ag)/anthracene phoswich for simultaneous α, β(γ) and fast-neutron counting and ZnS(Ag)/anthracene/NS8 phoswich for simultaneous α, β(γ), fast- and thermal-neutron counting. Satisfactory properties of pulse-shape discrimination among the respective radiations are presented in this paper.
