Outline of Final Research Achievements

This research focused novel treatment technique for soil polluted by radioactive cesium from accident of Fukushima Daiichi Nuclear Power Plant. In this research, water mixed with carbon dioxide was used for soil treatment. We developed on-site treatment and monitoring system for the polluted soil. In case of artificial polluted soil added by cesium 133, cesium was removed by mixed with containing water. However, water of pH 2 was required for remove radioactive cesium 134 and 137 from polluted soil collected at Fukushima area.
