核动力站向环境排放的放射性物质在核工业排放量中占相当大的部分。本文收集了国内外关于核动力站对公众的剂量当量限值、压水堆电站排放量限值及实际排放量等方面的数据,试图推荐符合我国实际的、合理可行的排放量限值,为制订我国核动力站辐射防护标准提供依据。 Radioactive substances emitted by the nuclear power station to the environment constitute a substantial part of the nuclear industry’s emissions. This paper collects the domestic and foreign data on the equivalent dose limits of nuclear power stations to the public, the limits of the PWR discharges and the actual emissions, and tries to recommend emission limits that are realistic and feasible for China. Formulate China’s nuclear power station radiation protection standards provide the basis.
