この日英協力では、放射性Cs,Co及びSrの回収に関わる新規の材料を2つの観点から開発する。一つめは、回収した放射性核種を原位置にとどめるために好塩性微生物を磁性化することであり、もう一つは汚染箇所への吸着材料の運ぶために易動性を増した材料を開発することである。

This joint JAEA/U. Birmingham research is built on the work of an established internationally leading collaboration for the development, characterization, and testing of two novel systems for immobilization of Cs, Sr and Co. The novelty of the first set of materials is that they are designed to be controlled by magnetized materials along with the recovered radionuclides in situ by halophilic organisms. This material could therefore be used in decontamination of harbor seawater of the FDNPP. The second novel materials are designed to be poured or injected into the ground to form porous barriers that will trap the targeted radionuclides and prevent further migration.
