RADIOACTIVE CESIUM COLLECTING MATERIAL, MANUFACTURING METHOD OF RADIOACTIVE CESIUM COLLECTING MATERIAL, RADIOACTIVE CESIUM COLLECTING METHOD, AND SOLIDIFICATION METHOD OF RADIOACTIVE WASTE
PROBLEM TO BE SOLVED: To provide a radioactive cesium collecting material having a high collection performance of radioactive cesium.SOLUTION: The radioactive cesium collecting material is a cement hardening body having a surface of a pH lower than 8 at which a phenolphthalein solution is not colored by carbonation, or its ground product, and the surface collects underwater radioactive cesium. Preferably, the form of the collecting material is powder, a grain, a member having an uneven surface, a vessel having an uneven surface, or a structure having an uneven surface.SELECTED DRAWING: None
【課題】放射性セシウムの捕集性能に優れた放射性セシウム捕集材を提供する。【解決手段】炭酸化により、フェノールフタレイン溶液が呈色しないｐＨが８未満の表面を有するセメント質硬化体またはその粉砕物であって、該表面が水中の放射性セシウムを捕集する、放射性セシウムの捕集材であり、好ましくは、該捕集材の形態が、粉体、粒体、表面に凹凸を施した部材、表面に凹凸を施した容器、または、表面に凹凸を施した構造物である。【選択図】なし
