STUDY OF RADIONUCLIDE COMPOSITION AND COEFFICIENTS OF RADIOACTIVE EQUILIBRIUM BETWEEN THEM IN URANIUM CHEMICAL CONCENTRATES

This article presents the results of identification of the radionuclide composition - 234U, 235U, 238U and the coefficients of radioactive equilibrium - Krr between - 234U/238U in uranium chemical concentrates. In laboratory conditions, the radionuclide - 234U, 235U and 238U composition of uranium chemical concentrates was identified. The radionuclide composition is determined by the total specific activity of the samples. This total specific activity of the samples creates the total power of the effective dose of gamma radiation at a given, local point. Each radionuclide in the uranium chemical concentrate has its own specific activity. 238U-has 1.25. 104 Bq/g, 234U-has 2.31. 108 Bq/g, 235U-has 7.91. 104 Bq/g. As can be seen from the data provided, 234U-has the highest value of specific activity. For this reason, it is relevant to conduct a study to study the radionuclide composition of uranium chemical concentrates. Based on the calculated theoretical formulas, the coefficients of radioactive equilibrium - Krr between - 234U/238U in uranium chemical concentrates were found. In addition, the relationships between the value of the radiation background of the storage site of uranium chemical concentrates and the values of the coefficients of radioactive equilibrium - Krr between - 234U/238U were studied.
