Study on 235U Transfer Depth in the Rubber

应用中子活化分析和γ谱测量方法,对铀场所中的橡胶、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。

The neutron activation analysis technology and γ spectrum analysis methods have been used to measure 235U relative intensity in the rubber and cable in the storage of uranium. 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 micrometers. 235U transfer depths are different for different materials and places. The results from the neutron activation analysis is as the same as that from of γ spectrum analysis.
