摘要：
It was found that the redistribution of Sr-90 in a soil with a disturbed profile was occurring by means of diffusion. The diffusion coefficients of Sr-90 increased at the contact of humus-enriched soil layers with the loamy illuvial horizon, which resulted in the predominant diffusion of Sr-90 down the soil profile.
