氚甄别测量技术研究进展

摘要

相同浓度的HTO和HT，ICRP给出它们的辐射危害比为10000：1。所以在不同组份氚源同时存在的情况下，必须进行氚甄别测量，以便为涉氚工作人员的辐射防护和环境安全评价提供合理有效依据。论文综述了国内外氚甄别测量技术的研究进展，着重介绍了氚甄别测量中不同组份氚源的各种分离方法及相应的探测技术，提出了氚甄别测量中存在的问题及下一步的发展方向。%Tritium may be present in air as tritiated water vapour ( HTO) or tritiated hydrogen gas ( HT).For purposes of people's radiation protection and environmental safety assessment , the airborne tritium concentration of each species should be determined separately since the two species represent very different radiological haz -ards.The paper reviews the research progress of discriminating measurement technology of tritium at home and abroad ,and introduces a variety of methods for the separation of different species of tritium and the correspond -ing detection technology .It also points out the problems in the discriminating measurement technology for tritium and proposes the direction of the further development .
