| 内容記述 | Soil-solution distribution coefficients (Kds, L kg-1) of 85Sr and 137Cs for three types of soil, i.e. Fluvisol, Andosol and Cambisol, were compared with Kds of stable Sr and Cs calculated from concentrations in water extractable and total fractions in the same soil samples. For all soil samples, Kd-85Sr and Kd-Sr ranges were 6.2x10^1-1.8x10^3 and 3.6 x10^1-1.8x10^4, respectively. Kd-85Sr and Kd-Sr in the three soil types were significantly different (p<0.05), but the difference between the geometric means of Kd-85Sr and Kd-Sr in each soil type was only two-fold. There was a weak correlation between Kd-85Sr and Kd-Sr. For cesium, Kd-137Cs and Kd-Cs ranges were 2.7x10^2-3.6x10^4 and 4.5x10^2-9.0x10^4, respectively. The difference in Kds for radioactive and stable Cs for the three soil types were less significant compared to those for Sr. A weak correlation was also observed between Kd-137Cs and Kd-Cs. Although the Kd measurement methods were different between radionuclides and stable elements, the data were similar and showed weak correlations. Thus the Kds of stable Sr and Cs in soil could be used as analogues of their radionuclides if there are no available data. | |||||
