简述了辐射对屏蔽材料的一般要求,着重介绍了防护X射线、γ射线、中子射线的屏蔽材料的种类和屏蔽原理以及稀土作为屏蔽材料的独特优势,指出稀土/高分子复合材料在X射线屏蔽应用中可有效弥补铅的弱吸收区;提出了屏蔽材料发展方向是研究添加稀土合金的复合材料,并努力提高这些稀土元素在复合材料中所发挥的作用来提高其屏蔽效果。
The general requirements of radiation shielding materials are briefly described. The types and shielding principles of shielding materials for shielding X-ray, γ-ray and neutron radiation as well as the unique advantages of rare earth as shielding materials are introduced. It is pointed out that rare earth / Radiation shielding applications can effectively make up for the weak absorption area of lead. The development direction of shielding materials is proposed to study the addition of rare earth alloy composite materials, and efforts to improve the role of these rare earth elements in the composite material to improve its shielding effect.
