The invention relates to area of reveal of sources of radio-active pollution. The method for registration of quick neutrons includes transformation of a cascade of gamma-quantums formed as result of inelastic scattering of neutrons in material of converter with high atomic number to series of light flashes with scintillator, processing of signals obtained at registration of those light flashes, formation of counter pulses with frequency proportional to neutron flux and registration of those by respective algorithm. At that one uses inorganic scintillators with high effective number as material of converter. To provide inelastic scattering of quick neutrons one uses materials with high atomic number that are included to the set of those inorganic scintillators. Processing of the signals obtained one carries out through integration of those with integration constant 30mcs, and formation of counter pulses one carries out through selection of integrated signals in power range equivalent to 10-300 keV. Inorganic scintillator in which as converter material with high effective atomic number is used are crystals BGO, GSO, ZnWO, CWO, Cs(Tl), Na(Tl), Li(Eu). Technical result of the invention is in increase of effectiveness of registration of neutrons and simplification of structure. |
