Soil-Soil Solution Distribution Coefficients for Se, Sr, Sn, Sb, And Cs in Japanese Agricultural Soils
- Office of Biospheric Assessment for Waste Disposal, National Institute of Radiological, Sciences, Chiba City (Japan)
In this study, soil-soil solution distribution coefficients (K{sub d}s) 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-K{sub d} data did not have a normal or a log-normal distribution, but Sr-, Sn-, and Cs-K{sub d} data did have a log-normal distribution. Further, Se-, Sr-, and Cs-K{sub d} 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 K{sub d} values for each radionuclide and soil properties. The combination of the K{sub d} value and the soil property having the highest correlation coefficient (Rs) for each radionuclide was as follows: Se-K{sub d} - concentration of water soluble P (R{sub s} = -0.51); Sr-K{sub d} - concentration of water soluble Ca (R{sub s} = -0.57); Sn-K{sub d} - concentration of water soluble Sr (R{sub s} = 0.57); and Sb-K{sub d} - concentration of water soluble P (R{sub s} = -0.67). Although there were no soil properties which had a good correlation with Cs-K{sub d} values for all soil samples, the best correlated soil property with Cs-K{sub d} values was concentration of water soluble ammonium ion (R{sub s} = -0.48) for upland soil samples.
