The migration of deposited radionuclides of Cs, Sr and U on soils could take place to the local environment. From this viewpoint, it is necessary to determine the distribution coefficients of Cs, Sr and U in the soil-water system around FDNPS. Sorption Kd(S) and desorption Kd(D) coefficients has been estimated using the laboratory batch method for the soils collected from Fukushima prefecture including Namie and Okuma Towns. High values of sorption coefficients for Cs and U implied sorption capacity of soils for Cs and U was more than Sr. The difference between sorption coefficient values of Cs and U was less in Okuma Town soils unlike to other soils. For Cs and U, Kd(D) was higher than Kd(S) whereas for Sr, Kd(S) was either equal to or higher than Kd(D). Overall, it revealed that unsorbed Sr could migrate farther than unsorbed Cs or U under the present experimental conditions., 福島大学環境放射能研究所第8回成果報告会}, title = {Sorption-desorption coefficients of Cs, Sr and U in contaminated soils collected around Fukushima Daiichi Nuclear Power Station}, year = {2022} }
