| Abstract: | The radionuclides strontium and cesium have a long half-life and large biological harmfulness and other characteristics, and become one of the key point on the safety of radioactive waste treatment disposal, and the removal of them by mineral has become a research hotspot. This paper introduces the characteristics and harms of the strontium and cesium. The research progress of four typical potential mineral materials in this field including hollandite, apatite, perovskite and pollucite are reviewed in detail. The status and development of strontium and cesium immobilization with mineral material are discussed. Finally, the future development trends of strontium and cesium incorporated by mineral materials are also mentioned. |
