Radioecological situation in Racha-Lechkhumi region of Georgia (Ambrolauri, Oni, Lentekhi, Tsageri districts) and annual effective doses of external irradiation of population have been studied. It was found that outdoor radiation background in Racha-Lechkhumi region is 58.0-169.0 nGy/h; average index is 108.9 nGy/h. Indoor radiation background is 68.0-192.0 nGy/h; average index is 137.4 nGy/h. The average annual effective dose of external irradiation of population in Racha-Lechkhumi region is 0.81 mSv/y, which exceeds the dose of similar type registered in most of countries. The implementation of adequate preventive measures for its reduction is required.
