摘要：

The Cs-137 radioactivity of soils was used as a tracer of soil erosion in a catchment in the Netherlands: 143 samples were analysed to map the Cs-137 redistribution using geostatistical interpolation methods. Caesium-137 activities on grassland are significantly higher than on arable land. Also, Cs-137 activities on waning slopes are higher and activities on steep slopes are lower. The soil erosion estimates, derived from the Cs-137 data, are used to validate the USLE erosion model. The recent Chernobyl nuclear accident also contributed to the Cs-137 activity. However, the Chernobyl input of Cs-137, with a constant ratio of 1.765:1 to Cs-134, cannot be used as a tracer of soil erosion. Because of the rapid decay of Cs-134, we will not be possible to separate the sources of Cs-137 in the near future in areas significantly influenced by Chernobyl fallout and in these areas Cs-137 can no longer be used as a soil erosion tracer.
