摘　　要：由于在实验过程中频繁操作氚钛源(TiT源),造成了实验室氚污染。专门的氚污染监测机构用氚表面污染测量仪进行监测,发现有遮挡物遮挡、不容易污染到的地方污染水平比容易污染到的地方还高,这是不合常理的一种异常现象。经过分析发现,污染异常的地方常年受氢(氘)气放电源照射,这种异常很可能与气体放电有关,论文给出了假设性解释。Laboratory was contaminated by tritium since TiT radioactive source was used continually.Measure used tritium contamination apparatus discovered that region sheltered was contaminated more seriously than region exposed.It is a abnormal phenomenon.analysis found that the region contaminated seriously was irradiated by hydrogen discharge source.The abnormal phenomenon likely relate to hydrogen discharge source.The article present an hypothetical explanation.

关 键 词：TiT源 氢(氘)气放电源 氚污染
