伴生放射性矿开发利用企业内γ辐射空气吸收剂量率分布研究——以某稀土厂为例

Study on the Distribution ofγ-Radiation Air Absorbed Dose Rate in Associated Radioactive Mine Development and Utilization Enterprises——Take a Rare Earth Factory as an Example

伴生放射性矿开发利用企业从事伴生矿产资源开发利用活动,其间,物料的天然放射性核素超过本底水平。在生产过程中,不同工艺流程和不同工作岗位的γ辐射空气吸收剂量率差异比较大。本文通过监测某稀土厂不同车间、不同岗位的γ辐射空气吸收剂量率,研究伴生放射性矿开发利用企业不同工作岗位的辐射水平,并提出相应辐射防护措施。

Associated radioactive mineral development and utilization enterprises are engaged in the development and utilization of associated mineral resources,during which the natural radionuclide of the material exceeds the background level.In the production process,the air absorbed dose rate ofγ-radiation varies greatly between different processes and different jobs.By monitoring the air absorbed dose rate ofγ-radiation in different workshops and positions of a rare earth plant,this paper studies the radiation levels of different jobs in the associated radioactive mine development and utilization enterprise,and proposes corresponding radiation protection measures.
