Abstract

On the basis of published data on the Altai region and Altai National Republic, including new materials of measurement beta-activity precipitations at 24 meteorological stations of Khakasia, Tyva, Buryat Republic, Irkutsk region and the south of Krasnoyarsk region, data of geological expeditions on recording increases of the radiation background, and instrumental measurements of sediment density and soil content of man-made radionuclides, a general picture of radiation influence of nuclear tests in the Semipalatinsk testing ground on South Siberia has been obtained.
