摘要
以自制的聚酰亚胺(PI)为基体、硝酸铅为添加剂制备了PI/硝酸铅辐射防护材料,重点利用高纯锗γ谱仪对该材料的辐射屏蔽性能进行测试分析,研究了硝酸铅含量对材料屏蔽性能的影响,并对热性能和耐辐射性能进行了测试。结果表明,该材料具有较好的耐辐射性能和屏蔽性能,可广泛地应用于多种领域。
Polyimide（PI） prepared by self as matrix and lead nitrate as additives,PI/lead nitrate radiation shielding material was prepared.The radiation shielding property of the material was tested and analyzed especially by HPGE coaxial detector system and the influence of content of lead nitrate on the radiation shielding property was studied.The thermal property and radiation resistance of the material were also investigated.The results indicated that the radiation shielding material had better radiation resistance and radiation shielding property and could be widely used in various fields.
