摘要
目的对某医院医学影像中心项目职业病危害放射防护及其控制效果进行分析与评价,以保障放射工作人员、患者或受检者和周围公众的职业健康与安全。方法采用放射卫生学调查、辐射水平检测、个人剂量监测、职业健康检查、统计学分析等方法,对放射机房屏蔽设施放射防护控制效果、设备安全装置、辐射检测水平、放射设备质量控制检测及放射卫生管理等进行分析与评价。结果该医院医学影像中心放射防护设施和放射卫生管理措施基本符合国家相关标准要求。放射机房外辐射水平检测结果范围在0.13~0.17μSv/h。放射工作人员个人剂量监测年有效剂量在0.10~1.92 mSv之间,2016年人均年有效剂量较2015年有所升高(t=-2.27,P<0.05)。放射设备质量控制检测结果符合相关标准。放射机房中为受检者配备的个人防护用品数量不能满足防护需要。结论该医院医学影像中心按要求整改后正常运行,能够保障放射工作人员、患者或受检者和周围公众的职业健康与安全。
Objective To analyze and evaluate on the radiation protection and control effect of occupational disease hazard in a hospital medical imaging center project,to ensure the occupational health and safety of radiological workers,patients or subjects and the surrounding public.Methods Using the methods of radiation hygiene investigation,radiation detection,personal dose monitoring,occupational health examination,statistics analysis,the radiation protection control effect,equipment safety device,radiation detection level,quality control inspection of radiation equipment and radiological health management of the hospital were analyzed and evaluated.Results The radiological protection facilities and radiological health management measures of the hospital medical imaging center are basically in line with relevant national standards.The radiation level of the radiating equipment room was 0.13~0.17 μSv/h.The effective dose of radiation workers was 0.10~1.92 mSv,and the effective dose per year in 2016 was higher than that in 2015（t=-2.27,P0.05）.The test results of radiological equipment quality control are consistent with relevant standards.The number of personal protective articles can not meet the needs of patients in the radiation room.Conclusion The medical imaging center of the hospital,which is required to be overhauled,will be able to ensure the occupational health and safety of radiation workers,patients or subjects and the surrounding public.
