某水池贮源γ射线辐照建设项目职业病危害放射防护预评价

Pre-assessment of radiological protection of occupational hazards in γ ray irradiation construction project of a pool

目的对某水池贮源γ射线辐照装置职业病危害进行放射防护预评价,从源头控制或消除职业病危害,防治职业病,保护放射工作人员和公众健康。方法根据国家相关的法律法规及放射卫生标准,采用理论估算、现场调查以及检查表分析等方法进行综合评价。结果该项目的辐照装置设计、工作场所布置基本合理;辐射安全符合国家相关标准要求;放射人员和相关公众接受的最大剂量估算值小于建设单位有效剂量管理目标值要求。结论该建设项目的放射防护设施设计基本符合国家规定。

[ Objective ] To evaluate the radiological protection of occupational hazards of γ ray irradiation equipment of a pool, control or eliminate the occupational hazards from the source, prevent and control occupational diseases and protect the health of radiologic workers and the public. [ Methods ] According to relevant national laws, regulations and radiological health standard, theoretical estimate, filed investigation and check list analysis were adopted to synthetically evaluated. [ Results ] The irradiation equipment design and workplace arrangement of this project are reasonable, radiation safety accords with the requirements of relevant national laws, maximum dose of radiologic workers and the public exposure is less than the target value of effective dose of construction pro- ject. [ Conclusion] The design of radiological protection facilities of this construction project accords with the national regulation.
