Abstract |
The content of natural radioactive elements in soils can be determined from their concentrations in the parent rocks from which the soils inherit the mineralogical and chemical composition. Data on the natural radioactive elements are reviewed in a profile of a soil-geographic division of the Komi ASSR in modern alluvial, ancient alluvial, and glaciofluvial deposits, blanket and moraine loams, and in eluvial-deluvial deposits of the Dvina, low-mountain Timan, Pechora, and mountainous Ural soil provinces. In addition, change in the content of natural radioactive elements in certain deposits that form under the influence of the outpouring of waters with elevated contents of natural radioactive elements onto an old surface is traced. |
