Abstract

Detection efficiency of fast and thermal neutrons was studied for detectors based on scintillators LiI(Eu), CWO, BGO, GSO, ZnWO4, CsI(Tl), ZnSe(Te), used in systems for detection of fissionable substances. Results are presented of our studies aimed at practical application of an efficient method for detection of fast and thermal neutrons, which uses the process of inelastic scattering on atom nuclei present in inorganic scintillators. The most evident practical application field for this method is inspection systems for prevention of illegal transportation of radioactive substances.
