Abstract
The redistribution of Chernobyl Cs-137 within a small drainage basin was st udied in the Lokna river basin, Tula region, Central Russia. Sheet erosion on the cultivated part of basin is the main reason for Cs-137 horizontal mi gration. However there is no statistically significant Cs-137 redistributio n within cultivated field because of relatively low erosion rates. The vall ey bottom is the main sink of Cs-137, where 73-84% eroded soil is stored. T he resulting Cs-137, level in the valley bottom is 1.5-2 times that of the initial Cs-137 fallout.
