STUDY OF THE RADIONUCLIDE COMPOSITION OF URANIUM CORE SAMPLES AND THE RADIATION SITUATION AT THEIR STORAGE SITES
Annotatsiya
This article presents the results of the study of the radionuclide composition of uranium cores and the radiation situation at the sites of their storage. In the samples of uranium cores, the radionuclide composition of the uranium decay chain was determined, especially the concentration of - 238U by X-ray fluorescence analysis and the specific activity of - 226Ra by gamma spectrometric analysis. Based on the data obtained, the coefficients of radioactive equilibrium - Kr between - 226Ra / 238U in the samples of uranium cores were determined. In addition, the radiation situation at the sites of their storage was studied, which has interrelations with the values of the coefficient of radioactive equilibrium - Krr between - 226Ra / 238U. The obtained results are compared with the standardized data established in International (ICRP, IAEA, UN, WHO, etc.) and Republican (SanPiN, O`zDst, GOSTs, etc.) documents
