Radionuclide content in the environmental objects (water, soil) and food has been studied in Ambrolauri, Oni and Lentekhi districts of Ratkha-Lechkhumi region, Georgia. Defined internal and total irradiation doses for the population and proposed preventive measures for its reduction were detected. Internal irradiation dose for the population due to K-40 was identified as 2,72 mSv/y, total irradiation dose – 3,87 mSv/y. To reduce the total irradiation dose of a population it is necessary to prohibit the use of high activity water for drinking; provision of the population with new sources of low activity water; minimize and control of irradiation doses from artificial sources including means of regulation of medical radiological procedures and rational use of fertilizers with K-40 content.
