An external exposure from 137Cs deposited on the surface soil is one of the important exposure pathways after an accident in a nuclear facility. In our previous study, it was found that the ratio of rapid component to total activity was most important parameter for dose estimation by using a 2-component removal model from surface soil. In this study, the differences of the probability density functions of the ratios of rapid components due to soil types was investigated by using the monitoring data on the concentration of 137Cs in the surface soil layers around the Chernobyl Nuclear Power Plant. It was discovered that the probability density functions of the ratios of rapid components vary with the soil types and these differences cause the differences in estimated values of integrated dose. This result indicated that information on soil types was useful for the reduction of uncertainty of dose estimation.
