摘要
通过对安徽某企业氧化锆生产过程中涉及的原料、产品及周边环境气溶胶中放射性核素含量进行调查研究,掌握了氧化锆生产过程中放射性核素的迁移途径以及对周边环境的辐射影响情况.研究结果表明,原料中的放射性核素在生产过程中主要迁移至硅粉中,迁移至其他产品中的放射性核素份额较小;对周围公众的主要影响途径为吸入含放射性核素粉尘产生的内照射,所占份额约为 99%.该研究结果为此类伴生放射性矿企业的辐射安全管理提供理论依据,为辐射监管部门的监管和决策提供数据支持.
Abstract
Radionuclide migrate and radiation effects of the surrounding environment are discussed based on analysis of radionuclide content in feedstocks,products and ambient aerosol in the production process of zirconia in an enterprise in Anhui Province.The results show that the radionuclides in feedstocks mainly migrate to silica fume during the production process.The main impact on the surrounding public is the internal irradiation produced by inhalation radionuclide-containing dust which is about 99%.The results of this study provide theoretical basis for the radiation safety management of radioactive mining enterprises and data support for the supervision and decision-making of radiation regulatory authorities.
