| 目的 分析2020—2022年新乡市部分医院介入放射工作人员眼晶状体剂量和年有效剂量水平, 掌握介入放射工作人员眼晶状体剂量和年有效剂量水平现状。方法 通过热释光剂量测量技术,采用整群随机抽样原则,2020—2022年连续3年对新乡市6家医院的介入放射工作人员进行眼晶状体剂量Hp(3)和年有效剂量Hp(10)测定,分析各年度不同医院级别、不同科室介入放射工作人员眼晶状体剂量和年有效剂量水平。结果 3年累计有效监测117人次,眼晶状体年当量剂量左眼为0.12~164.24 mSv、右眼为0.07~51.64 mSv,3年累计人均年当量剂量左眼8.56 mSv、右眼4.49 mSv,左、右眼年当量剂量分布在探测下限(MDL)~5 mSv范围内的比例分别为60.68%、73.50%,有9.41%(11人次)的介入工作人员左眼晶状体年当量剂量超过20 mSv;年有效剂量范围为0.11~31.27 mSv,3年累计人均年有效剂量为2.56 mSv,年有效剂量主要分布在MDL~1.25 mSv的比例为52.14%,有2.56%的介入工作人员年有效剂量超过20 mSv;3年累计人均左、右眼晶状体剂量和年有效剂量三级医院与二级医院相比,差异无统计学意义(P＞0.05); 3年累计人均剂量不同科室相比,差异均具有统计学意义(H=11.42、13.72、25.94,P＜0.05), 其中神经内科眼晶状体剂量及年有效剂量低于心内 科和综合介入科(Z心内科=-3.33、-3.78、 -4.83,P＜0.05;Z综合介入科=-2.71、-2.63、-4.39,P＜0.05)。结论 新乡市介入放射工作工作人员眼晶状体年当量剂量和年有效剂量大部分符合国家限值标准,但有部分人员剂量较高且有超出国家限值的现象;提示在常规监测年有效剂量的同时加强介入放射工作人员眼晶状体常规、连续性的剂量监测,关注二级医院介入放射工作人员眼晶状体及年有效剂量,提高防护意识。 |

| Objective To analyze the eye lens dose and annual effective dose to interventional radiation workers in some hospitals of Xinxiang city from 2020 to 2022, and to ascertain the dose to interventional radiation workers. Methods By using TLDs, the eye lens dose Hp(3) and annual effective dose Hp(10) were monitored for three consecutive years in six hospitals in Xinxiang city. The lens doses and annual effective doses to intervention radiation workers in different years in different-level hospitals and departments were analyzed. Results From 2020 to 2022, a total of 117 people were monitored. The left eye lens dose range was 0.12-164.24 mSv, and the right eye lens dose range was 0.07-51.64 mSv. The average annual dose was 8.56 mSv for left eye lens and 4.49 mSv for right eye lens The average annual dose distribution in the MDL-5 mSv range for the left and right eye lens was 60.68% and 73.50%, respectively. 9.41% (11 people) of the left eye lens doses exceeded 20 mSv. The annual effective doses range was 0.11-31.27 mSv, with average annual dose of 2.56 mSv. The proportion of average annual effective doses mainly distributed in the range of MDL to 1.25 mSv was 52.14%, with 2.56% annual effective dose exceeding 20 mSv. There was no significant difference in left and right eye lens dose and annual effective dose between the tertiary hospitals and the secondary hospitals in three years (P＞0.05). Compared with different departments, the cumulative per capita dose in three years was statistically significant (left eye H=11.42, right eye H=13.72, annual effective dose H=25.94, P＜0.05). The lens dose and annual effective dose in neurology department were lower than those in cardiology department and comprehensive intervention department (Zcardiology department=-3.33, -3.78, -4.83, P＜0.05; Zcomprehensive intervention department=-2.71, -2.63, -4.39, P＜0.05). Conclusions Most of the annual equivalent dose and annual effective dose to eye lens of the interventional radiation workers in Xinxiang city meet the national limits, but some of them have higher doses and exceed the national limits. It is suggested that the routine and continuous monitoring of eye lens doses to interventional radiologists should be strengthened while routine monitoring of annual effective dose, and attention should be paid to the eye lens and annual effective dose to interventional radiologists in secondary hospitals to improve the awareness of protection. |
