摘　　要：目的分析南通市某三甲医院介入放射工作人员2009-2017年个人剂量以及现场辐射状况,为保障医院介入放射工作人员健康提供数据支撑。方法介入放射工作现场辐射剂量率检测采用辐射检测仪(AT1123),个人剂量检测系统采用热释光剂量仪(RGD-3D、FJ-427A)。结果该三甲医院2台介入设备透视防护区测试平面空气比释动能率为39.74~492.48μGy/h、17.28~198.72μGy/h,2009-2017年介入放射工作人员年个人剂量值均高于普放科室工作人员(2015年除外),差异具有统计学意义。结论介入放射科机房内的辐射剂量率要明显高于机房外,介入手术的工作人员个人剂量要明显高于其他放射工作人员。因此,介入放射工作人员应当正确佩戴个人防护用品科学操作介入放射设备。Objective To investigate the individual dose and radiation situation on site of interventional radiology staff in a third-grade class-A hospital in Nantong city from 2009-2017,so as to provide data support for the health protection of interventional radiology staff in the hospital.Methods The X-γRay radiation dose detector(AT1123)was used for the dose rate detection of interventional radiology on site,and the individual dose detection system(RGD-3D、FJ-427A)was used for individual dose detection.Results The air kerma rate of fluoroscopic protective zone of the two interventional radiology machine were 39.74~492.48μGy/h and 17.28~198.72μGy/h,and the annual individual dose value of interventional radiology staff was higher than that of general radiology staff(except 2015)from 2009 to 2017,and the difference was statistically significant.Conclusion The radiation dose rate in the room of interventional radiology department was significantly higher than the outside the room,and the individual dose level of interventional surgical staff was obviously higher than that of other radiological staff.Therefore,interventional radiology staff should wear personal protective equipment correctly and operate interventional radiology equipment scientifically.
