Studying the possibility of applying spectral methods for the analysis of chemical elements and radionuclides

Abstract

This article presents the results of a study of the possibility of using spectral methods for analyzing chemical elements and radionuclides. As is known, in uranium production processes, chemical elements and radionuclides behave differently and they are distributed in different concentrations. Therefore, the main tasks of analytics are to determine the concentration and specific activity values of chemical elements and radionuclides in samples taken from various uranium products of uranium production. The magnitude of radiation factors at a local location of a uranium product is assessed by determining the values of these factors and the amount of various radionuclides contained in these samples. In laboratory conditions, the concentrations of U were determined by X-ray fluorescence analysis, the specific activity of 230Th, 226Ra, 40K and 137Cs was determined by gamma spectrometric analysis, and the isotope concentrations of 234U, 235U, 238U were determined by alpha spectrometric analysis. The results obtained were compared with the passport data of standard samples - SOUR, OSK-6, OSK-9, OSGI. Determining the concentration and specific activity values of various chemical elements and radionuclides in uranium products is of scientific and practical interest, and solving this issue is an urgent task of nuclear physics and analytics.
