【摘要】 应用中子活化分析和γ谱测量方法,首次对多年存储高浓铀（HEU）场所中的橡胶、橡皮和电缆中²³⁵U的迁移深度进行了研究,结果表明,²³⁵U在橡胶介质中的迁移深度为几十到几百微米;对于不同场所,不同用途的材料中U的迁移深度不同。两种方法获得的结果一致。更多还原

【Abstract】 We use the neutron activation analysis technology and γ spectrum analysis method to measure ²³⁵U relative intensity measurement in the rubber and cable placed the storing of HEU. This is the first time to make study on ²³⁵U transfer depth in the rubber and cable. The result shows that ²³⁵U migration depth between tens and hundreds micrometer. In different materials and different places,²³⁵U transfer depth are different from.. The results of the neutron activation is analysis as same as one of r spectrum analysis更多还原
