ABSTRACT
The results of research of horizontal migration of 137Cs with soils water erosion are presented. It was found that quantitative parameters of 137Cs migration depended on radioactive pollution of cultivated soil layer, volume of water erosion of soils and character of usage of sloping lands. Activity of 137Cs in lower parts of slopes was 37-295 kBq/m2 higher than in the middle and apex parts of slopes. Increase in 137Cs activity varied from 10 to 18 percent in accumulation zone as compared to outwash zone with soil losses 5.0 t/ha and from 17 to 35 percent with soil losses 5.1-10.0 t/ha and from 30 to 127 percent with soil losses 10. 1-20.0 t/ha.
