摘要
目的掌握河北省内核医学诊疗项目职业病危害放射防护评价情况及存在的问题,提出可行性的建议。方法收集2011-2018年期间受委托的32个核医学建设项目的职业病危害放射防护评价的相关资料和正式报告,主要从项目一般情况、选址及周围情况、布局流程以及放射性废物管理等方面进行分析,并提出可行性的意见和建议。结果 32个核医学建设项目中含预评价23个、控制效果评价9个;核医学建设项目主要集中在三级医院,有13家(占72.33%),其次是民营医院有3家(占16.67%);有5个(占15.6%)项目的选址不合理,建议项目单位强化屏蔽防护以及加强对放射性废物和用药后患者的管理;在初次提交的布局流程图中发现医、患、核素路线交叉,功能用房缺失,以及三区划分混乱等问题共79次,经放射防护评价,相关问题减少到18次,其中三区划分混乱和内部路线交叉问题都得以解决;项目初始资料中对气态放射性废物的管理存在的一些问题,经过放射防护评价也都得到了较好的解决。结论建设项目职业病危害放射防护评价对于核医学建设项目是从源头上控制放射性污染、保护人员及环境安全的重要措施,需要引起建设单位和相关管理部门的高度重视。
Objective To know the evaluation situation and existing problem of occupational disease hazard radiation protection evaluation of nuclear medical treatment project in Hebei province, and put forward some feasible suggestions.Method To collect relevant information and official reports on the occupational hazard radiation protection evaluation in 32 nuclear medical construction projects commissioned from 2011 to 2018, mainly from the general situation of project, site selection and surrounding situation, layout process and radioactive waste management, and put forward feasible opinions and suggestions.Results Among the 32 nuclear medicine construction projects, 23 were pre-evaluated and 9 were evaluated for the control effect. Nuclear medicine construction projects are mainly concentrated on tertiary hospitals, with 13(72.33%), followed by 3 private hospitals(16.67%). Five(15.6%) of the projects were not properly located. It is suggested that project units should strengthen shielding protection and strengthen the management of radioactive waste and patients after drug administration. In the layout flow chart of the initial submission, it was found that there were 79 problems such as the intersection of medical, patient and nuclide routes, the lack of functional rooms, and the confusion in the division of the three zones. After the radiation protection evaluation, the number of related problems was reduced to 18. Among them, the division of the three zones and the intersection of internal routes have been resolved. Some problems in the management of gaseous radioactive waste in the initial data of the project have been well solved after radiation protection evaluation. Conclusion Radiation protection assessment of occupational disease hazards in construction projects is an important measure for nuclear medical construction projects to control radioactive pollution and protect personnel and environment safety at the source, which needs to be paid great attention by the construction units and relevant administrative d
