To understand the occupational external exposure dose among radiation workers in a firstclass hospital at Grade 3 of Suzhou, and to provide reference for radiological protection. The 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. From 2010 to 2017, the total annual collective effective dose was 351.40 personmSv, 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 (>0.05) . Most of radiation workers have low individual dose level in the hospital. It is important to focus on nuclear medicine workers and interventional radiology workers.
了解苏州某三甲医院放射工作人员的职业外照射剂量，为放射防护提供参考。对该医院2010年至2017年1156名放射工作人员的个人剂量进行检测，分析不同年份、不同职业（诊断放射学、放射治疗、核医学、介入放射学）、性别及年龄的年集体有效剂量和人均年有效剂量。2010年至2017年，年集体有效剂量总计351.40人·毫希沃特，人均年剂量为0.30毫希沃特/年，年有效剂量小于1毫希沃特的放射工作人员占94.98%。有5名介入放射学工作人员和1名核医学工作人员的年有效剂量在2至4毫希沃特之间。无年有效剂量超过4毫希沃特的工作人员。核医学工作人员的人均年有效剂量最高（0.40毫希沃特/年）。不同性别和年龄的放射工作人员人均年有效剂量差异无统计学意义（>0.05）。该医院大部分放射工作人员个人剂量水平较低。重点关注核医学工作人员和介入放射学工作人员很重要。
