本文研究了氚(HT)和氚水(HTO)在用于聚变设施建设的材料上的吸附和解吸。在氩气或室内空气中暴露约24小时，金属样品吸附8-200{Mu}Ci/m{sup 2}(1Ci=3.7{次}10{sup 10}Bq)氚形成5-9 Ci/m{sup 3}HT的大气，非金属样品从14 Ci/m{sup 3}HT的大气中吸附60-800{Mu}Ci/m{sup 2}。不同样品对HTO的吸附比对HTO的吸附范围大得多，从玻璃的4Mu Ci/m~(Sup2)到室内空气中的1,300,000{Mu}Ci/m~(Sup3)HTO。干燥空气中解吸的时间依赖性表现为快速的初始过程和较慢的二次过程。
In this paper, sorption and desorption of tritium (HT) and tritiated water (HTO) on materials to be used in the construction of fusion facilities are studied. In ca. 24-hour exposures in argon or room air, metal samples sorbed 8-200 {mu}Ci/m{sup 2} (1 Ci = 3.7 {times} 10{sup 10} Bq) of tritium form atmospheres of 5-9 Ci/m{sup 3} HT, and non-metallic samples sorbed 60-800 {mu}Ci/m{sup 2} from atmospheres of 14 Ci/m{sup 3} HT. Sorption of HTO varied much more widely than HT sorption for different samples, ranging from 4 {mu}Ci/m{sup 2} for glass to 1,300,000 {mu}Ci/m{sup 3} HTO in room air. Time dependence of desorption in dry air showed a rapid initial process and a slower secondary process.
