| 内容記述 | Distributions of C-14 in solid, liquid, and gas phases were determined by batch sorption tests using 142 Japanese agricultural soil samples. The agricultural soils used were classified into "paddy" and "upland" soils. Each of the soil samples was suspended in deionized water containing [1, 2-C-14] sodium acetate and shake-incubated for 7 days. After the incubation, the distributions of C-14 in solid, liquid and gas phases were approximately 35%, 5% and 60% of the spiked C-14, respectively. These results suggested that if the C-14 of acetate migrated from a TRU repository site to agricultural soils, most of the C-14 would be released into the air and the rest would be distributed in the soil solid phase. The distribution of C-14 in gas phase was lower for upland soils than for paddy soils. | |||||
