在氚工艺研究、氚生产等涉氚场所，如何快速准确收集操作间和烟囱流出物中的氚对工作人员辐射防护和氚排放量的控制非常重要。针对涉氚场所氚以氚气（ HT）和氚水（ HTO）两种形态存在的特点，基于半导体冷阱研制了一套HTO－HT甄别式氚快速取样系统。该取样系统设置了高热效率催化氧化炉和运行自控装置，采用低温冷阱冷凝收集经过催化氧化床氧化后的HT。系统取样流量为0～10 L／min时，催化效率＞99％，取样效率＞95％，能够满足涉氚场所对HTO和HT甄别式快速取样的要求。

How to quickly and accurately collect the tritium of the operating room and chimney exudate is one of the key points to the radiation protection of staff and the control of tritium emission in the tritium target produc -tion, tritium factories and other involved tritium places .On the base of the appearance of the tritium as tritium gas(HT) and tritium water(HTO) , the fast tritium sampling system for discriminating HT and HTO was devel-oped based on semiconductor cold trapping .A thermally efficient catalytic oxidation furnace and controlled de-vice were designed , and the tritium gas through catalysis oxidation was collected with a low -temperature cold trapping.The results indicate that when the sampling flow is 0~10L/min, the catalytic efficiency is more than 99%and the sampling efficiency is more than 95%.This sampling system can meet the need of the fast tritium sampling in involving tritium places .
