Abstract
The article considered problem of exposure of population to natural radioactive gas radon and its daughter decay products. Shown differences in geological and radioecological conditions that determine formation of volumetric activity radon in territory of eastern regions of Republic of Belarus, are quantitatively expressed in
a complex radon index. Values of average annual effective doses exposure of population from radon estimated by models ICRP and UNSCEAR for Vitebsk region accord 1.49 ± 0.09 mSv/year and 2.45 ± 0.15 mSv/year; for Gomel region is 0.60 ± 0.04 mSv/year and 0.99 ± 0.06 mSv/year; for Mogilyov region is 1.30 ± 0.09 mSv/year and 2.14 ± 0.14 mSv/year respectively.
