Large area detector of low-energy gamma radiation
Detectors for registration of low-energy gamma radiation based on plastic scintillator UPS-923A with composite YSO:Ce and CsI:Tl layers were developed. Size and concentrations of granules in the composite scintillators were determined experimentally. Additional composite layer in the detector design...
