目的为核实某医院介入放射工作人员的大剂量受照情况,保障放射工作人员的健康与安全。方法通过调查其工作量、测量工作位置的剂量率和受照剂量来分析查找人员受照剂量偏高的原因。结果被调查单位防护用品性能良好,但由于工作人员未能正确佩戴剂量计以及部分人员工作量相对较大,以致其个人剂量偏高。结论要加强介入放射学中放射工作人员的防护与安全管理,正确佩戴剂量计,合理安排工作量,尽量避免一些工作人员受到较高的剂量照射。
The purpose is to verify the radiation exposure of a large hospital staff to ensure the health and safety of radiation workers. Methods By investigating the workload, measuring the working position of the dose rate and exposure dose to find the cause of the higher staffing doses. Results The unit under test showed good performance. However, the personal dose was too high due to the staff not properly wearing the dosimeter and the relatively heavy workload of some staff. Conclusion It is necessary to strengthen the protection and safety management of radiation workers in interventional radiology, wear the dosimeter correctly, arrange the workload reasonably, and try to avoid some workers being exposed to higher dose.
