Effect of cations and particle size on radiocesium distribution in Fukushima soils

摘要

The migration of~(137)Cs in the environment is mainly affected by the suspended soil particles of various sizes.In order to study the distribution of radiocesium and exchangeable cations in Kawauchi soils we analyzed~(137)Cs and exchangeable cations.The main objective of this study is to determine the distribution of~(137)Cs,~(40)K in the soil in relation to the cations by explicitly analyzing activity concentration of~(137)Cs,~(40)K and exchangeable Na~+,Mg~(2+),K~+,and Ca~(2+)concentration in various soil particles.In addition,we looked on the effect of iron in Fukushima soils.
