城市库废放射源治理工作中的剂量控制

摘要

Disused radiation sources management work of city radiation waste storage vaults has its own characteristics.In the processing of the work,there are many factors which can influence the dose of staff.Some statistical results and implementation experience were got in the past management work of national city radioactive waste storage vaults.For the optimization of radiation protection,the characteristics and different radiation risks of the work were analyzed,combined with the statistical results and implementation experiences.Reasonable dose control methods were proposed for different risks.Besides that,we also collected and analyzed the dose data of the past management work of national city radioactive waste storage vaults.Some dose distribution characteristics were found,which can guide the radioprotection and provide a reference for the later work.%城市放射性废物库废放射源治理过程中影响工作人员受照剂量的因素较多.为实现辐射防护的最优化,本文以全国城市库治理项目统计结果及现场实施经验为依据,分析了城市库废源的特点、辐射风险及剂量控制方法.并对城市库废源治理项目的剂量数据进行统计分析,发现剂量分布规律,为辐射防护工作提供指导和参考.
