摘要

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