| Outline of Final Research Achievements |
Large amounts of radioactive materials were spread over a wide range by the accident of Fukushima Daiichi nuclear power plant occurred. Currently, the decontamination of radioactive materials discharged by this accident is urgently needed. However, the efficient and effective decontamination technology is not established. It is necessary to achieve the extraction of the cesium that firmly fixed to the clay mineral in soil and the volume reduction of disposal materials so as to base our prediction on the decontamination. In this study, the test was conducted to examine the extraction characteristic of cesium and the adsorption property of an adsorbent material. From the test, it is turned out that there is not most changes in extraction characteristics even if the passage of time is changed, and that the used adsorbent has a very high adsorption ability.
