Application of the geosynthetics materials with cesium sorption abilities for remediation of radioactive contamination: Part II

Abstract

The health damage by the diffused radioactive cesium from the Fukushima disaster to the inhabitants has been deeply concerned. Therefore radiation decontamination works for residential houses and their vicinity have been conducted. However, even after decontamination works, the periphery of forests faces potential risks of re-rising radioactive dosage brought by wind and rain. Last year we proposed a method that geosynthetics with an absorbing function of radioactive cesium laid on the ground of the decontaminated areas aforementioned restrains the transition of radioactive cesium1). This report presents the one-year-after results: Effectiveness of radioactive cesium absorbing function of the method to restrain radioactive cesium is confirmed by increase of the amount of radioactive cesium in the geosynthetic materials.
