摘　　要：在放射性核素走向分析和环境现状调查的基础上,对某氯化法钛白粉生产项目的放射性环境影响进行了分析、预测与评价。放射性环境现状调查表明,评价因子总体在区域环境本底范围内,经分析确定了放射性敏感点。经放射性环境影响预测,工作人员和公众所受的附加剂量分别为0.59mSv/a和9.28×10-4mSv/a,均低于年有效剂量管理限值。在落实辐射防护和环境保护措施并加强放射性环境监测后,该项目的放射性环境影响符合国家有关法规和标准限值要求。Based on the analysis of shifting direction of radionuclide in production process and the environmental investigation and monitoring,the radioactive environmental impact from a production project of titanium dioxide by chlorination process has been analyzed and assessed.The result of radioactive environmental investigation shows that values of assessment factors are in the range of environmental radioactive background.The radioactive environmental sensitive spot has been delineated.The results of radioactive environmental prediction show that the additional doses to workers and residents are 0.59 mSv/a and 9.28×10^-4 mSv/a respectively which are less than the annual dose limits of administration.The radioactive environmental impact of the production project of the titanium dioxide by chlorination process will meet the needs of national regulations and standards if radiation protection and environmental protection measures are implemented and radioactive environmental monitoring are strengthened.
