摘要
分析了^(85)Kr的性质及其在环境中的迁移行为,对气态流出物和环境介质中^(85)Kr的测量方法进行了总结。研究表明,对核电厂气态流出物和空气、水样品中的^(85)Kr,需要经分离纯化进行样品制备,并在液闪谱仪上测量,以获得足够低的探测限。对^(85)Kr的剂量评估方法进行了研究,采用目前我国主流机型CPR1000、AP1000和华龙一号的排放源项进行估算,表明核电厂释放的^(85)Kr对公众造成的辐射剂量极小。
In this paper, the characteristics and environmental behavior of ^85Kr released from NPP are presented. The analytical methods for ^85Kr in gaseous effluents from NPP and in environmental samples （including air and water） are also investigated and summarized. Our research indicated that the most effective analytical method for ^85Kr in effluents and in low-level air and water is Liquid Scintillation Spectrometer （LSC） with a series of separation and purification procedures. Meanwhile, the atmospheric dispersion factors of ^85Kr were studied using typical release source terms for the CPR1000, AP1000, and Hualong One reactor types. The results indicated that the exposure dose to the public would be extremely small.
