[Hygienic assessment of irradiation doses of Mtskheta-Mtianeti region' population]

Radionuclide content in the food and water in Mtskheta-Mtianeti region of Georgia has been studied, internal and total irradiation doses for the population have been defined and preventive measures for its reduction were detected. Internal irradiation dose for the population due to (40)K was identified as 1,58 mSv/y, total irradiation dose (external and internal irradiation) - 2,57 mSv/y, that is to some extent high than acceptable levels. 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 (40)K content.
