【摘要】 针对 L i F- TLD在 n-γ混合场的区分测量、抗核辐射加固实验和辅助核查时 ,存在 TL D吸收剂量响应的 LET效应问题 ,开展了 TLD对中子响应的 L ET效应实验研究。研究工作从实际应用角度出发 ,优选了目前国内重现性指标最好的 L i F- TL D探测器 ,设计了从热中子至 14Me V中子的辐照装置 ,进行了严格的实验测试和必要的理论计算 ,得出了 Li F- TLD对较宽能区中子响应的 LET效应因子。其结果可用于 n- γ混合场的区分测量、抗核辐射加固实验和核查。更多还原

【Abstract】 With regard to the LET effect problem of TLD absorbing dose respond existed when dose test for LiF TLD is done n γ mixed field, the paper do experimental rescarch on LET dependence property of TLD respond. From the phase of practical application, the rescarch work select prioriorty LiF TLD detector which has so far the best re appearing index in China, designs radiation equipments for thermal neutron to 14 MeV neutron, dose strict experiment test and necessary theoretical calculation, and then acquire LiF TLD LET effectfactors to neutron. LET effect factors tested by experiments can be used in identification test for n γ mixing field and nuclear checking.All these basically reach the requirements of the paper.更多还原
