摘要: 对国家标准《稀土工业污染物排放标准》水污染物放射性排放控制要求提出了质疑,因稀土工业水污染物排放中放射性物质不只含铀钍,且大部分含有相当浓度的镭及其子体。建议参考GB 23727—2009《铀矿冶辐射防护和环境保护规定》和世界卫生组织颁布的《饮用水水质准则》,以及《稀土工业污染物排放标准》中水污染物放射性排放控制要求列入镭等相应子体相关内容:在第一取水点的限值, U为0.03 mg/L、232Th为1 Bq/L、228Ra为0.1 Bq/L、226Ra为1 Bq/L,并列出车间废水排放口的相应控制要求。

Abstract: Due to the existence of radium along with uranium and thorium in waste water, the truth of radioactivity limits for waste water set in GB 26451—2011“Emission Standards of Pollutants from Rare Earths” was questioned. Referencing to the GB 23727—2009 “Regulations for Radiation and Environment Protection in Uranium Mining and Milling”, the paper suggests an inclusion of Ra series in GB 26451—2011, with specific limits as U 0.03 mg/L, 232Th, 228Ra, and 226Ra is 1.0, 0.1 and 1.0 Bq/L respectively in waste water from product line or plant.

Key words: rare earth, waste water, radioactivity, limit
