| Research Abstract |
Contamination of radioactive Cs for surface environment is serious in Fukushima Prefecture.It is important to know how the Cs will recirculate in the environment. In the processes, microbe-mineral interaction will play a significant role. Examining many constituent materials containing microbe-mineral interaction, it was clarified that bacteria strongly accumulate Cs in bacterial body. Accumulation and dissolution of Cs in caly minerals and organic materials were also experimentally examined. The accumulation of Cs in the bacteria was directed observed by TEM. Accumulation of two types was clarified. Based on other experimental results, future re-circulation of Cs in the environment was discussed based on a proposed model figure.
