摘要

~(137)Cs accumulation in soil profiles from 0-30 cm depth were measured in different land uses (forest, banana orchard ,cashew orchard and pine apple plantation) in the Huai Raeng-Klongpid Watershed, Trat Province,Thailand. Soil samples from differentland uses were selected at 3 sampling points at 5 cm intervals to 30 cm deep. The ~(137)Cs activity in the soil samples was determined by gamma spectrometry using a High Purity Germanium (HPGe) detector. The ~(137)Cs accumulation in soil in the forest,banana orchard, and cashew orchard and pine apple plantation were 16.4, 14.8,12.3 and 11.2 Bq/kg, respectively. The results from this study implied that ~(137)Cs accumulation for different land uses is related to soil erosion. Therefore,~(137)Cs technique could be used as a tool for soil erosion evaluation in Thailand
