| 内容記述 | Radiocaesium mobility in 40 agricultural soil samples at different temperature conditions (4-30˚C) was studied by measuring the soil-soil solution distribution coefficient, Kd (L/kg). Comparison of Kd values obtained at 10˚C and at 30˚C indicated significant differences for 36 soil samples by the one-way ANOVA test (p<0.05) with decreases in Kd values under the higher temperature condition. The Kd measurement at 4˚C was intended to minimize the soil microbial activity effect; the results were almost the same as those observed at 10˚C. From this result, it was difficult to identify the effect of microbial activity on the radiocaesium absorbability to the soil solid phase. The obtained data imply a possible seasonal change of Kd values in many types of soils, and the Kd change likely affects the radiocaesium release rate change from soil to river water during a year. | |||||||||
