Abstract
In order to study the possibility of removing radioactive cesium (Cs),134Cs and 137Cs, accumulated on the soil surface, a column device of Cs-contaminated soil overlaid on non-contaminated soil was constructed. The movement and distribution of radioactive Cs in soil by pouring various solutions were analyzed with an imaging plate. Further analysis of the chemical composition of the droplets from the device and in the soil after the experiment was reported to investigate the effects of the soil. It was found that most radioactive Cs are effectively transferred by acidic solutions such as 2 M citric acid and 10% polyphosphoric acid, and the impact on soil is not so great.
