Cesium is a radioactive fission product generated in nuclear power plants and is disposed of as liquid waste. The recent astrophe at the Fukushima Daiichi nuclear plant in Japan has increased the 137Cs and 134Cs concentrations in air, soil and water to lethal levels. 137Cs has a halflife of years, while the halflife of 134Cs is around two years, therefore the formersrsquo ...

Distribution of radioactive cesium varies depending on the status of soil such as cracks and as a result of decontamination work or deep plowing. Clayey soil contains clay minerals such as vermiculite, which strongly adsorb cesium. Cesium adsorbed in such clayey soil becomes hardly soluble in water and is fixed and retained near the surface layer of the soil for a long term. Accordingly ...
