摘　　要：目的分析苏州市某三甲医院放射工作人员外照射个人剂量情况,为放射防护工作提供参考。方法选择苏州市某三甲医院放射工作人员作为调查对象,采用回顾性调查方法,收集2010至2017年共1 156人次个人剂量监测数据,分析不同年份、工种(诊断放射学、放射治疗、核医学、介入放射学)、性别和年龄的放射工作人员年集体有效剂量和人均年有效剂量。结果2010至2017年该医院放射工作人员年集体有效剂量为351.40人·mSv,人均年有效剂量为0.30 mSv/年。年有效剂量<1 mSv的人次数占监测总人次数的94.98%,5例介入放射学工作人员和1例核医学工作人员年有效剂量为2~<4 mSv,未发现年有效剂量≥4 mSv的监测数据。核医学工作人员人均年有效剂量最高(0.40 mSv/年)。不同性别、年龄放射工作人员人均年有效剂量差异均无统计学意义(P>0.05)。结论该医院放射工作人员个人剂量处于较低水平,应重点关注介入放射学和核医学工作人员。ObjectiveTo understand the occupational external exposure dose among radiation workers in a first-class hospital at Grade 3 of Suzhou, and to provide reference for radiological protection.MethodsThe individual dose of 1156 radiation workers in the hospital from 2010 to 2017 were detected, the annual collective effective dose and per capita annual effective dose were analyzed for different years, different occupations (diagnostic radiology, radiotherapy, nuclear medicine, interventional radiology) , gender, and age.ResultsFrom 2010 to 2017, the total annual collective effective dose was 351.40 person·mSv, the per capita annual dose was 0.30 mSv/a, and radiation workers whose annual effective dose was less than 1 mSv accounted for 94.98%. There were 5 interventional radiology workers and 1 nuclear medicine worker with annual effective dose between 2 and 4 mSv. There was no worker with annual effective dose over 4 mSv. The per capita annual effective dose of nuclear medicine workers was the highest (0.40 mSv/a) . The per capita annual effective dose was not significantly different between radiation workers with different genders and ages (P>0.05) .ConclusionMost of radiation workers have low individual dose level in the hospital. It is important to focus on nuclear medicine workers and interventional radiology workers.
