This article presents the results of a study of the relationship between the increase in the radiation background in uranium production facilities and the coefficient of radioactive equilibrium between the radionuclides of the uranium decay chain. A theoretical calculation formula for the mixing of daughter radionuclides is given and, based on this formula; the mixing distance between daughter radionuclides in the uranium decay chain is calculated. It has been established that the reason for the increase in the radiation background in uranium production facilities is the violation of the radioactive equilibrium between radionuclides.

“…There are many nuclear-physical factors that are the causes of violations of the radioactive equilibrium between these radionuclides, such as the age of minerals, migration coefficients of radionuclides, geochemical factors, recoil energies, geotechnology conditions of leaching, etc. [10][11][12][13][14][15][16].…”

Natural radioactivity is a public health issue that affects people all around the world. Environmental radioactivity accounts for approximately 87% of the radiation dose received by human beings. The primary external source of irradiation to the human body is gamma radiation emitted by naturally occurring radioisotopes such as 40K and radionuclides from the 232Th and 238U families, as well as their decay products, which exist at trace amounts in all ground formations. The establishment of baseline data for environmental radiological studies is of great importance for the assessment of environmental radiological levels in Uzbekistan and related studies on human health risks. The current study aimed to describe the research state of the art on natural radioactivity in Uzbekistan with emphasis on results obtained during the last 20 years. NaI (Tl) and High Purity Germanium HPGe detectors were employed in most conducted studies. The results showed that data for natural radionuclide activity were below international standards in all but a few areas. The research results of this paper can play a good guidance and reference role in the planning of such research in the future.

The purpose of the article is to describe monitoring studies on the radiation state of air in populated and working areas near the uranium processing enterprise in the Republic of Uzbekistan. Ac-cording to the analytical measurement, the exposure dose of gamma radiation is equivalent to the equilibrium volume activity of radon, specific activity of long-lived alpha-emitting nuclides in the zone of influence of the enterprise, the working area, premises for storing uranium materials and manufacturing dumps, tailings dams and areas of underground uranium leaching. It was shown that the measurement results do not exceed the regional background and regulatory levels of radioactive radiation by all indicators. The dependence of the volume activity of radon at production facilities on the density of the radon flux from the soil was studied. The most intensive radioactive objects – uranium dumps – were identified. It was found out that there is no excess radioactive impact of the uranium enterprise on the environmental objects.
