固相材料在放射性碘高效捕获中的研究进展

Research Progress of Solid Phase Materials in Efficient Capture of Radioactive Iodine

核能作为一种高效、清洁的能源在各领域具有广泛的应用,然而在核能开发利用过程中,放射性核素不可避免地释放并残留到环境中,对人类和生态环境造成严重威胁。其中放射性碘具有超长的半衰期(129I)、高活性、易在环境中积累等特点,会对生态系统造成严重安全隐患。基于此,本文综述了国内外放射性碘吸附材料,总结了国内外现有材料优缺点,为固相吸附材料在气载放射性碘吸附的应用中提供新思路。

Nuclear energy is widely used in various fields as an efficient and clean energy.However,in the process of nuclear energy development and utilization,radionuclides are inevitably released and remain in the environment,posing a serious threat to humans and the ecological environment.Radioactive iodine has the characteristics of ultra-long half-life(129I),high activity and easy accumulation in the environment,which will cause serious safety hazards to the ecosystem.Based on this,this paper reviews the radioactive iodine adsorption materials at home and abroad,summarizes the advantages and disadvantages of existing materials at home and abroad,and provides new ideas for the application of solid phase adsorption materials in the adsorption of airborne radioactive iodine.
