摘要/Abstract

摘要： 鉴于国家标准《核动力厂环境辐射防护规定(GB 6249—2011)》表1中仅给出不区分核素的、以年排放活度(Bq/a)表示的“碘”和“粒子”排放控制值,造成核动力厂气载放射性排放限值与公众个人年剂量不匹配,难于执行或执行混乱。为解决此问题,提出采用区分核素的方法,并监测对剂量贡献较大的重要核素的建议。根据IAEA第19号安全报告,探讨了核动力厂气载放射性流出物中碘类和粒子类的重要核素,为标准补充或修订提供建议。

Abstract: It is easily resulted in performance confusion problem with discharge limit value and public annual dose doesn't match under the Regulation for Environmental Radiation Protection of Nuclear Power Plant (GB 6249—2011) for Nuclear Power Facility (Plant) monitoring. Because of its contents in table 1 only gives discharge limit value indiscriminating specific nuclide in particle and iodine type. To solve this problem, the author suggests to discriminate specific nuclide and with monitoring focus on key nuclides as major dose contributor. According to the IAEA No.19 safety report, the author works out the important nuclides in particle and iodine type in NPP airborne radioactive effluents.

Key words: airborne radioactive effluents, annual dose, effluents monitoring, dose conversion factor
