【摘要】 [目的]了解上海市闵行区宠物医院X射线诊断机房的放射防护水平与管理情况。[方法]对闵行区11家宠物医院X射线诊断机房管理情况及放射工作人员防护知识掌握情况进行问卷调查,对机房环境与工作人员个人剂量水平进行检测。[结果]11家宠物医院均未执行新建、改建、扩建X射线诊断机房三同时原则。放射工作人员规范培训率70%,放射防护知识知晓率75%;防护用品配备率100%,电离辐射警告标志配备率73%,工作状态指示灯正常使用率55%。X射线诊断机房平均面积(5.8±2.7)m2,机房防护检测合格率82%。放射工作人员人均年有效剂量0.73 m Sv/a。[结论]该区宠物医院X射线诊断机房的辐射防护水平较低,放射工作人员防护知识不足,内部管理有待加强。更多还原

【Abstract】 [Objective] To evaluate the protection and management levels of dignostic X-ray rooms in pet hospitals in Minhang District, Shanghai. [Methods] A questionnaire survey was conducted in 11 pet hospitals on management of X-ray equipment rooms serving diagnostic purpose and veterinary radiologists’ protection awareness. The radiation levels of radiation equipment rooms and veterinary radiologists were also measured. [Results] None of the 11 pet hospitals followed the triple simultaneousness principle(design, construct, and acceptance) of building, altering, or expanding radiation equipment rooms. The standard training rate among radiation workers was 70%, and the awareness rate of radiological protection knowledge was 75%. The rates of pet hospitals providing protective equipment, posting ionizing radiation warning sign, and routinely using good-working indicator light were 100%, 73%, and 55%, respectively. The average area of the radiation equipment rooms was(5.8±2.7) m2. In addition, 82% of the radiation equipment rooms were in accordance with the national standards, and the average effective dose among radiation workers was 0.73 m Sv per year. [Conclusion] The radiation protection levels of radiation equipment rooms, veterinary radiologists’ protection awareness, and internal management levels need to be strengthened.更多还原
