The digital method efficiency for analysis of neutron channel loading for various scintillation counters

The paper studies the efficiency of digital method for analyzing the loading of neutron channel for liquid and crystalline scintillators. Two different sources of gamma quanta have been used and the dependence of the change in the number of registered neutron pulses on the distance to the source of gamma quanta has been determined. It has been shown that for the BC-501 scintillator, in comparison with the EJ-309 scintillator and a stilbene crystal scintillator, up to a loading of 3 ∙ 104 pulses / s, the number of detected neutrons remains unchanged and the responses of gamma quanta do not fall into the responses of neutrons, which ensures the efficiency of the digital registration method of neutron radiation.
