Outline of Final Research Achievements |
Cesium desorption behavior was investigated for Cs-fixing weathered biotite under oxic or anoxic conditions. Although changes in Fe status from ferrous to ferric and increase in the structural distortion of Cs-fixing biotite were confirmed through weathering under oxic condition, cesium desorption was not occurred. In contrast, cesium desorption from the biotite was progressed under anoxic condition, suggesting that soil-to-plant transfer risk of 137Cs may increase under anoxic conditions as in paddy field.
