摘要
目的了解宝鸡市介入放射学工作人员眼晶状体及手部剂量水平,为辐射防护提供一定的数据参考。方法选取2家综合医院,2021—2023年对其121人次介入放射学工作人员进行眼晶状体和手指剂量监测,分析不同年度、岗位、手术部位和术中职责人员人均年剂量水平和剂量分布情况。结果眼晶状体人均年剂量为3.36mSv,最高剂量为16.36mSv;手指人均年剂量为3.38mSv,最高剂量为17.72mSv,2021—2023年眼晶状体和手指人均年剂量呈下降趋势。介入医师眼晶状体人均年剂量高于技师和护士,介入医师手指人均年剂量高于技师;第一术者与第二术者眼晶状体和手指人均年剂量相当,但均高于参与介入手术的其他人员,差异均有统计学意义(均P<0.05)。介入放射学工作人员眼晶状体和手指年剂量与全身有效剂量存在线性回归关系;不同手术部位介入人员的眼晶状体和手指年剂量配对进行检验,心血管和外周血管介入人员眼晶状体人均年剂量高于手指,脑血管介入人员手指人均年剂量高于眼晶状体,差异均有统计学意义。结论介入放射学工作人员眼晶状体和手指年剂量均低于国家限值,但部分人员眼晶状体年剂量接近国际新标准限值(20mSv)。应重点关注介入医师,尤其是介入手术第一、第二术者。
Objective To investigate the eye lens and hand dose levels of interventional radiology workers in Baoji City,China,and to provide data reference for radiation protection.Methods In two general hospitals,the eye lens and finger doses of 121 interventional radiology workers were monitored between 2021 and 2023.The average annual dose levels and dose distribution were analyzed based on years,job positions,surgical sites,and duties during surgery.Results sTheaver-age annual dose to the eye lens was 3.36 mSv,with the highest dose of 16.36 mSv.The average annual dose to the fingers was 3.38 mSv,with the highest dose of 17.72 mSv.The average annual dose to the eye lens and fingers decreased from 2021 to 2023.The average annual dose to the eye lens of the interventional surgeons was higher than those of the technicians and nurses,while the average annual dose to the fingers of the interventional surgeons was higher than that of the technicians.The average annual doses to the eye lens and fingers of the first operator were similar to those of the second operator,but both were higher than other personnel involved in the interventional surgery,and the differences were statistically significant(all P<0.05).There were linear regression relationships between the annual doses to the eye lens and fingers and the effect-ive whole-body dose of the interventional radiology workers.A paired test was conducted on the annual dose to the eye lens and fingers of the interventional workers for different surgical sites.The cardiovascular and peripheral vascular intervention-al workers had higher average annual doses to the eye lens than to the fingers,the cerebrovascular interventional workers had a higher average annual dose to the fingers than to the eye lens,and the differences were statistically significant.Conclusion The annual doses to the eye lens and fingers of the interventional radiology workers in Baoji City were lower than the national limits.However,some workers showed eye lens annual doses close to the new international standard limit(20 mSv).Special attention should be given to interventional physicians,especially the first and second surgeons.
