摘　　要：综述了国内外关于沉降再悬浮因子/率估算方法的研究进展,筛选出五种较广泛应用的再悬浮因子/率的估算方法,并利用切尔诺贝利核电站事故后^(137)Cs再悬浮因子/率监测数据,分析比较以上五种估算方法。结果表明:IAEA推荐方法的估算结果在实际测量结果的范围内,适宜于再悬浮因子/率的估算,可作为沉降再悬浮因子/率估算方法深入研究以及放射性污染场地环境风险评估源项计算的技术基础。The research progress of sedimentation re-suspension factor/rate estimation methods at home and abroad is summarized,five widely used resuspension factor/rate estimation methods were selected,and 137Cs resuspension factor/rate monitored of Chernobyl nuclear power plant accident was used. The above five estimation methods are nalyzed and compared. The results show that the estimated results of the IAEA recommended method are within the scope of the actual measurement results and the method are suitable for the estimation of the resuspension factor/rate. They can be the technical foundation used as an in-depth study of the sedimentation re-suspension factor/rate estimation method and the source estimation of environmental risk assessment for radioactively contaminated sites.
