Ten years have passed since the 1F accident that occurred in 2011, and the contaminated soil generated in Fukushima Prefecture is being stored as removal soil at an intermediate storage facility. In the process of developing the technology to remove cesium from the soil, we have focused on the functionality of the crystalline minerals after the removal of cesium, and have been investigating their potential as thermoelectric conversion materials. In this study, we report the results of evaluation of thermoelectric 3 properties (electrical conductivity, thermal diffusivity, Seebeck coefficient) of crystalline minerals.
