description: This work is devoted to the study of scintillation gamma spectrometers produced by STC "RADEK" and GC "GRINSTAR". The aim of the work is to develop a methodology for assessing the efficiency of pile-up rejector operation in scintillation gamma spectrometers. As part of the work, an analysis of scientific and technical information on the functioning of electronic pulse processing circuits was carried out, a method for determining dead time was selected and the efficiency of pile-up rejection was evaluated. As a result of the research, a solution to the problem was found, and based on the results obtained, a conclusion was drawn about the successful application of the developed methodology. The main design and operational indicators are: selection of a radionuclide that is a source of monoenergetic gamma rays (Cs137, K40, etc.), high input loads of the gamma radiation detector. This methodology provides the ability to quickly and conveniently assess the efficiency of pile-up rejector operation.
