| 内容記述 | In this study, soil-soil solution distribution coefficients (Kds) for five radionuclides (Se-75, Sr-85, Sn-113, Sb-124, and Cs-137) were determined by batch sorption tests in 142 Japanese agricultural soil samples (63 paddy soil and 79 upland soil samples). The results showed that Se- and Sb-Kd data did not have a normal or a log-normal distribution, but Sr-, Sn-, and Cs-Kd data did have a log-normal distribution. Further, Se-, Sr-, and Cs-Kd values differed between paddy and upland soil samples in t-test (p < 0.05). Spearman's rank correlation test was carried out to investigate correlations between Kd values for each radionuclide and soil properties. The combination of the Kd value and the soil property having the highest correlation coefficient (Rs) for each radionuclide was as follows: Se-Kd - concentration of water soluble P (Rs = -0.51); Sr-Kd - concentration of water soluble Ca (Rs = -0.57); Sn-Kd - concentration of water soluble Sr (Rs = 0.57); and Sb-Kd - concentration of water soluble P (Rs = -0.67). Although there were no soil properties which had a good correlation with Cs-Kd values for all soil samples, the best correlated soil property with Cs-Kd values was concentration of water soluble ammonium ion (Rs = -0.48) for upland soil samples. | |||||
