摘要
放射性元素锶和铯具有半衰期长、生物危害性大等特点,是目前放射性废物安全处理处置的重点之一,利用人造岩石固化含锶、铯放射性废物已成为当前的研究热点。简述了锶、铯的特点及危害,着重介绍了近年来几种典型矿物固化基材(碱硬锰矿、磷灰石、钙钛矿、铯榴石)的研究进展,探讨了现阶段矿物固化锶、铯的研究进展和发展方向,并对未来关于矿物固化锶、铯的材料领域发展趋势进行了展望。
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.
