摘　　要：综述了放射性污染土分选减容设备系统的研制现状。&先简述了放射性污染土分选减容工艺原理,然后重点介绍了国内外放射性污染土分选减容的设备系统研制现状,最后分析讨论了放射性污染土分选减容的关键技术和发展趋势。总结研究表明:适合我国场地特点的污染土放射性分选设备系统的研制,应重点关注放射性探测器的配置优化、本底抑制消除、测14-分选协同控制、合适的分选策略四个主要的技术问题。The development of equipment system for separating and reducing capacity of radioactive contaminated soil is reviewed.This paper briefly introduces the principle of separation and volume reduction process of radioactive contaminated soil.Then we mainly introduce the development status of the equipment system for separating and reducing the volume of radioactive contaminated soil at home and abroad.Finally,the key technology and development trend of the volume reduction of radioactive contaminated soil are discussed.The conclusion shows that in order to develop the radioactive contaminated soil sorting equipment system which is suitable for the characteristics of the site in China,we should focus on four major technical problems:the configuration optimization of the radioactive meter,the elimination of background suppression,the cooperative control between the measurement and sorting,and the appropriate sorting strategy.
