聚合物基中子及伽马射线防护材料研究进展

Research progress on polymer shielding composite for neutron and gamma ray

随着核工业和技术的发展,人们在享受其带来的便利的同时,又时刻可能受到来自核辐射的伤害。从20世纪60年代起,伴随着核技术的民用化,核辐射防护材料及其制备方法的研究也越来越多。从最常用的中子和伽马两种射线出发,概述了中子和伽马射线的防护机理,总结了现有防护材料制造方法和防护材料结构设计思想,最后对两种射线辐射防护材料未来的发展前景进行了展望。

With the development of nuclear industry and technology,people are exposed to the harm from nuclear radiation while enjoying the convenience from it.Since 1960s,with the popularization of nuclear technology,more and more researches on nuclear radiation protection materials and their preparation methods have been conducted.The protection mechanism for neutrons and gamma rays were introduced briefly.Then the manufacturing methods and structural design ideas of protective materials were summarized.Finally,the development prospect of the two kinds of radiation protection materials were expounded.
