Results of Implementation of the State Program ‘Radiation’ in Georgia
In the frames of the State program ‘Radiation’ radiation background of different regions of Georgia — Adjaria, Guria, Samegrelo, Imereti, Racha-Lechkhumi, Svaneti, Kartli, Kakheti, Samtskhe-Javakheti, Mtskheta-Mtianeti, Samachablo, city Tbilisi — has been studied. According to the results of the study radiation background of the open places is 70,8– 136 nGy/h, of the buildings — 96–160 nGy/h, an average annual external dose of iradiation of the population — 1,03 mZv/y (0,84–1,2 mZv/y), that is relatively high than analogous data of Europe. There have been found ‘hot’ spots, where dose of irradiation is nearly 300–440 nGy/h (mountain region of Adjaria). The most high doses of irradiation are in Svaneti and Racha-Lechkhumi regions — 1,2 and 1,15 mZv/y respectively. Despite the fact that high indicators of the radiation background is fixed only in single cases and, so their influence on average indicators of the radiation background is insignificant, we think that the detailed study of the mentioned territories (containing of radionuclides in the environmental objects, food and their identification) and also study of health state of the population are necessary.
