| 内容記述 | There was a large release of radio cesium (Cs-134 and Cs-137) to the atmosphere during Fukushima Daiichi Nuclear Power Plant (FDNPP) accident and contaminated soil, over a vast area, due to fallout activity. Therefore, studies on the behavior of radio cesium especially migration in soil and its retention on soil particles is very important for external dose assessment and root uptake. We have determined the sorption coefficient (Kd) for Cs using laboratory batch method in soil samples collected from a contaminated area affected by FDNPP accident and the effect of various soil parameters on the Kd value has been studied. We have noticed that Cs sorption is mostly influenced by cation exchange process and sorbed on the surface of clay particles. From vertical depth profile of Cs in soil, it is found that most of it is retained on the top layer within 5cm thickness. Sequential extraction of soil using various reagents may be helpful to understand better on the mechanism of Cs retention. |
