摘要：
A simple power-function equation was developed to relate changes in soil Cs-137 with time to an average annual soil-loss rate. The equation accounts for tillage dilution of the concentration of Cs-137 in the surface plow layer and for enrichment in the eroding soil. The predictions from the relationship were similar to values for a more complicated model and to measured values given in previous studies.
