实验室中氚的安全防护

Safety Protection of Tritium in Laboratory

氚是β放射性核素,分析测试过程中会释放到环境中,对人体产生内照射危害,需重视实验室中氚的安全防护。本文简要介绍了氚的性质,对实验室中氚的防护重点、防护措施及污染处理进行探讨,在管理制度、工作场所、实验用品、职业人员等方面采取有效的防护措施,可避免或减少氚通过各种途径进入人体,确保实验人员自身及实验室安全。

Tritium is aβradionuclide,which will be released into the environment during analysis and testing,causing internal exposure to the human.It is necessary to pay attention to the safety protection of tritium in the laboratory.This article brief ly introduces the properties of tritium,discusses the protection focus,protective measures and decontamination of tritium in the laborator y.The useful measures that is taken in the management systems,workplaces,laboratory supplies and experimenter can avoid or reduce the various channels that tritium gets into people's body,which can ensure the safety of the experimenter and the laboratory.
