Abstract

This study presents original data on the content of radionuclides of natural (cosmogenic and terrorogenic) and man-made origin in the assimilation apparatus of Scots pine (Pinus sylvestris L), which grows in the Western Caucasus (within the Karachay-Cherkessia Republic). The content of radioisotopes of beryllium (7 Be), potassium (40K), thorium (232Th), uranium (238U) and cesium (137Cs) was revealed in pine needles. Close correlation of radionuclide content in pine needles samples 7Be, 238U, 137Cs with the height of growing places was revealed.
