%X 在氚光源的应用中，氚泄漏率是衡量其安全性能的一个重要指标。由于氚对玻璃的渗透率很低，因此在氚光源没有破损的条件下，其氚泄漏量很低，难以通过传统的电离室探测技术直接测得。本文分别用电离室和液闪测量了常温下气体氚光源的氚泄漏率，结果表明在氚光源无破损的条件下，用电离室难以直接测得其氚泄漏率；而依靠液闪建立的测量方法，则可以准确地测得氚光源的氚泄漏率。<br />
In the application of tritium light source, the leakage rate of tritium is an important index to measure its safety performance. Because the permeability of tritium to glass is very low, the leakage amount of tritium is very low under the condition that the tritium light source is not damaged, which is difficult to be directly measured by the traditional ionization chamber detection technology. In this paper, the leakage rate of gas tritium light source at normal temperature was measured by ionization chamber and liquid scintillation counter respectively. The results show that the tritium leakage rate is difficult to be measured directly by ionization chamber under the condition that the tritium light source is not damaged. The tritium leakage rate of the tritium light source can be accurately measured by the method of liquid scintillation counter.
