FIELD: dosimetry of fast neutrons and gamma-radiation, possible use in stationary and portable radiation control devices, meant for finding radioactive materials.
SUBSTANCE: scintillation detector contains at least one scintillation block sensor, including plastic scintillator in form of prism or cylinder for registration of fast neutrons, made with at least one hollow channel and fibrous scintillation light guide positioned in it, light-reflecting mirror, photodiode photo-detecting device and a block for electronic signal processing.
EFFECT: increased efficiency of registration of gamma-radiation during simultaneous registration of fast neutrons with possible usage of multichannel photo-electronic multiplexers or compact photodiode devices as photo-registration means.
