中子屏蔽材料是一种具有快中子慢化性能的基体材料和具有吸收中子性能的吸收材料混合而成的屏蔽中子材料,目前已经广泛应用于医疗、农业、航空、核反应堆等领域。简述了中子屏蔽材料的一般要求,主要论述了多种类型的中子屏蔽材料现状和性能。对新型中子屏蔽材料进行了展望,指出开发具有随意裁剪、任意粘贴与包装性能与良好的力学和屏蔽性能相结合的柔性中子屏蔽材料是未来发展的趋势。
Neutron shielding material has been widely used in medical,agriculture,aviation,nuclear reactor and other fields.The general requirements for the neutron shielding material were outlined,discussed the current situation and performance of various types of neutron shielding material.In the end,the future of material was looked,pointed out it was the future trend that developed a flexible neutron shielding materials which not only had arbitrary cutting,random pasting,package performance,but also combined good mechanical and shielding performance.
