摘要
主要对X射线、γ射线及中子辐射屏蔽材料的种类、基质材料和屏蔽性能进行了全面的分析和综述。在此基础上,探讨了现有射线及中子辐射屏蔽材料存在的主要问题,如吸收效果不高、基质材料力学性能差、屏蔽性能与其他性能难以兼顾等。最后展望了辐射屏蔽材料的研究方向,指出开发多功能、轻质、高强的抗辐射屏蔽材料是未来的发展趋势。
The kinds, substrate materials, shielding properties of X ray, γ ray, and neutron radiation shielding materials are fully analyzed and reviewed. On this basis, the main questions of the existing ray and neutron radiation shielding material, such as the lower absorption, the poor mechanical properties of substrate materials and the shiel- ding properties difficult to balance with other performance and so on, are discussed. Finally, the research on radiation shielding materials is prospected. It is pointed out that the development of multi-functionah lightweight, high strength and resistance to radiation shielding materials is the future trend of development.
