中文摘要:
      核屏蔽实质是屏蔽γ射线和中子,本文详细介绍了γ射线和中子屏蔽材料目前的种类和性能,探讨了现有γ射线和中子屏蔽材料存在的主要问题,分析了各种屏蔽材料的屏蔽性能与不足之处,指出亟待解决的四个主要矛盾(综合屏蔽性能、力学性能、耐热性能及环保性能)。最后,展望了未来核辐射屏蔽材料的发展趋势,提出了随着反应堆技术的发展,功能/结构一体化屏蔽材料已成发展趋势,以及指明了稀土材料在防辐射屏蔽材料方面的应用应作为进一步研究的重点。
英文摘要:
      The main task for the nuclear shielding design is combining combined barrier against γ Gray and neutron. This paper offers an elaborate description of the types and performances of the currently applied γ Gray and neutron shielding material, and furthermore, roughly discusses the respective principal problems of these materials. The key problem that needs to be settled is the conflict between shielding effectiveness and other performances such as mechanical performance, heat-resistant stable anti-radiation property. At last the review sketches out the prospect of the γ Gray and neutron combined shielding materials, suggesting that the development of structure/function integrated radiation shielding materials is one of the future trends. It is noted that the application of rare earth materials in radiation protection should be the focus of further research.
