本文介绍用LiF(Mg,Ti)热释光探测器(TLD)的异常发光曲线测冠氚气瓶螺母上的氚表面污染结果,讨论了用氚钛靶源刻度氚β射线的IL响应的技术。在样品照射30h情况下,此方法的探测下限为400 Bq/cm~2。
In this paper, the results of tritium surface contamination on tritium gas cylinder nuts measured by abnormal luminescence curve of LiF (Mg, Ti) thermoluminescence detector (TLD) are introduced. The technique of tritium β ray IL response . The detection limit of this method is 400 Bq / cm ~ 2 when the sample is irradiated for 30 h.
