JAEA received technical proposals from private enterprise about techniques that can be used for decontamination work, and "Decontamination Technology Demonstrations Projects" was commissioned from the Ministry of the Environment to verifies the decontamination effect, economy feasibility, safety, and other factors. By the "FY 2013 Decontamination Technology Demonstrations Projects" JAEA carried out technical advice of demonstration test and evaluation of 11 technologies (e.g., decontamination of soils and green space and wastes and washing of fly ash).

Biotite inhibits radiocesium (RCs) transfer from soil to plants by two functions of selective adsorption of radiocesium (Cs) between layers (Cs adsorption ability) and K supply from between layers (K supply ability). However, it was difficult to distinguish between the two. In this study, the authors succeeded in preparing biotite in which both functions are variously different by preparing weathered biotite in which interlayer pottasium (K) was replaced with rubidium (Rb) to lose K supply ability. By systematically comparing these biotites, the authors clarified the effects of Cs adsorption ability and K supply ability on Cs transfer to plants.
