Uranium and Its Distribution in Typical
Belarusian Soils
Galina A. Sokolik, Svetlana V. Ovsiannikova, and Maryna V. Papenia
Abstract The background levels of uranium content in the soil cover of different
regions of Belarus are determined. Experimental data on the uranium content in the
samples of (0–20)-cm layers of different varieties of sod-podzolic, sod, and peat- bog
soils are presented. From analysis of the experimental data obtained, it follows that
the uranium content increases in the series of soils “sandy-sandy loamy-loamyclayey” as the content of fraction with the size of soil particles less than 10 μm
increases. Natural background concentrations of uranium in the environment differ
between various regions of the country. In accordance with the structure of the soil
cover, there is an increased content of uranium in the northern region of Belarus with
a higher proportion of loamy and clayey soils than in the southern region where
sandy and sandy loam soils occupy a significant part of the territory. Experimental
data on the uranium content in the soil interstitial (pore) water extracted from watersaturated soil samples by the method of high-speed centrifugation are presented. A
close direct relationship was found between the portions of uranium and organic
components in the soil interstitial solutions of their total content in mineral soil samples. The coefficients of uranium distribution between a solid phase and interstitial
solution of soils of different types were estimated. For individual varieties of soils, it
has been established how the uranium reserve in a mobile (conditionally biologically
available) form changes with a change in the temperature and humidity of the soil.
