【摘要】：目的:随着介入手术过程趋向复杂化,介入放射学工作人员受照的辐射剂量、时间也日益增加。因此,关于介入放射学工作人员的放射防护是目前广泛关注的问题。本研究通过监测介入放射学职业人员受照的职业辐射剂量,评估从事介入放射工作人员的年度职业辐射剂量水平。方法:回顾性分析本院2014—2015年介入放射学工作人员受照的职业辐射剂量(有效剂量与剂量当量),辐射剂量通过a、b两枚个人剂量计进行检测(a:一枚佩戴在外衣上;b:一枚佩戴在铅衣上)。结果:将本院于2014—2015年进行的介入手术筛选出2 202例,纳入本研究的介入放射学工作人员包括:6名介入医师、3名护士、3名放射技师,其年度有效辐射剂量分别为:3.00±1.50(0.84~6.17)mSv/y、1.34±0.55(0.70~2.20)mSv/y及0.60±0.48(0.02~1.43)mSv/y,剂量当量分别为:19.84±12.45(7.0~48.5)mSv/y、4.73±0.72(3.9~6.2)mSv/y及1.30±1.00(0.2~2.7)mSv/y。对于介入医师A组、A+B组的有效辐射剂量分别为:(1.02±0.74)mSv/y、(3.00±1.50)mSv/y(P0.001)。对于护士(P=0.186)与放射技师(P=0.186),A组较A+B组的有效辐射剂量均更低。结论:介入放射学工作人员年度受照的职业辐射剂量:介入医师护士放射技师。而A组的职业辐射剂量远远小于A+B组的。因此,为了正确评估职业辐射剂量,应使用a+b两枚个人剂量计进行监测、计算。
[Abstract]:Objective: with the complication of interventional surgery, the radiation dose of interventional radiology workers is increasing day by day. The radiation protection of interventional radiology workers is a widespread concern at present. This study monitored the occupational radiation dose of interventional radiology professionals. To assess the annual occupational radiation dose levels of interventional radiation workers. Methods: a retrospective analysis of the occupational radiation doses of interventional radiologists in our hospital in 2014-2015 (. Effective dose and dose equivalent). Radiation dose was measured by two personal dosimeters: one was worn on a coat; B: one piece was worn on a lead coat. Results: 2,202 cases were screened out for interventional surgery performed in 2014-2015. The interventional radiologists included: 6 interventional physicians and 3 nurses and 3 radiographers. The annual effective radiation doses were: 1: 3.00 卤1.50 卤0.84U 6.17mSv / y, respectively. 1.34 卤0.55 卤0.70 mSv / y and 0.60 卤0.48 mSv / y and 1.43 mSv / y respectively. The dose equivalent was: 1: 19.84 卤12.45mSv / y, 48.5mSv-y, respectively. 4.73 卤0.72 卤3.9n 6.2mSv / y and 1.30 卤1.00mSv-0.20.7mSv / y. for interventional physician group A. The effective radiation doses in group A and B were 1.02 卤0.74 mSv / y, respectively. For nurses (P = 0.186) and radiographers (P = 0.186). Conclusion: the annual occupational radiation dose of interventional radiology workers is: interventional physician and nurse radiographers, but the occupational radiation dose of group A is much lower than that of A. Group B. So... In order to evaluate occupational radiation dose correctly, two personal dosimeters (a / b) should be used for monitoring and calculation.

【正文快照】： 随着介入手术向着复杂化发展,手术操作过程中透视时间也随之增加,进而导致介入放射学工作人员及患者受照辐射剂量增加[1-10]。介入医师在手术过程中受到辐射诱导眼损伤的风险很大,应该加强介入工作人员眼部辐射防护进而避免白内障的发生[11]。2004年,Haskal等[12]研究发现59名
