Subject of study: radionuclide composition and specific activity of radionuclides, scaling factors. The purpose of the work is to substantiate the list of radionuclides for the flow of radioactive materials (ChNPP equipment and systems) that will be sent for exemption from regulatory control; scaling coefficients for hard-measured radionuclides from key radionuclide. Research methods: methods of measuring radiological characteristics and radiation parameters of radioactive materials; methods of mathematical statistics. Within the framework of the performed research work, the site of dismantling of equipment for which materials (carbon steel) are present, which can be released by termination in case of deactivation to the appropriate levels determined by hygienic standards, has been determined. Based on the criteria for attribution to a single stream, pieces of equipment arriving at a single stream were selected at the site. Taking into account the requirements of the document "Method of determination of nuclide vectors for radioactive materials of the Chornobyl NPP", a sampling program was prepared in accordance with which 95 paired metal samples were selected. Half of the selected samples were deactivated. which, theoretically, may be present in surface contaminated radioactive contamination. According to the results of the researches, calculations of scaling factors for decontamination Based on the statistical analysis, it is proved that the number of samples taken to substantiate the list of radionuclides and the calculation of scaling factors is sufficient.
