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 migration depth of 235U in rubber, eraser and cable in uranium was studied by neutron activation analysis and γ spectrometry. The results showed that the migration depth of 235U in rubber medium was several tens to several hundred micrometers. For Different sites, different uses of materials in the migration depth of U different.
