摘　　要：目的分析某医院放射工作人员3年个人剂量检测及职业健康数据,探讨不同职业类别受照剂量的差异以及放射工作人员防护效果。方法本研究对2020年1月—2022年12月山东省某3家医院所有放射工作人员共7440人次个人剂量水平、职业健康数据进行分析。结果从事介入医学工作人员其个人有效剂量分布区间明显高于其他从业人员,特别在>3.0 mSv区间介入医学3名,而核医学及诊断放射学各1名。但总体分析显示,从事核医学的放射工作人员个人剂量要高于其他职业类别,差异有统计学意义(P<0.05)。从事介入医学专业放射工作人员,其腹部B超异常率为42.31%,远高于平均水平的31.13%。核医学专业在血压、腹部B超等项目异常检出率显著高于其他职业类别(P<0.05)。结论2020—2022年,放射工作人员接收辐射剂量较多的是介入医学,其有效剂量分布区间相对较高,而核医学人均年有效剂量最高。同时,介入医学专业腹部B超异常率远高于平均水平,而核医学专业则在血压、腹部B超等项目异常检出率显著高于其他职业类别。Objective To analyze the three-year personal dose testing and occupational health data of radiation workers in a certain hospital,and to explore the differences in radiation doses received by different occupational categories and the protective effects of radiation workers.Methods This study analyzed the personal dose levels and occupational health data of 7440 radiation workers in a first class hospital over a period of three years.Results The study found that the personal effective dose distribution range of personnel engaged in interventional medicine was significantly higher than that of other practitioners,especially in the>3.0 mSv range of interventional medicine for 3 people,while in nuclear medicine and diagnostic radiology for 1 person each.But overall analysis showed that radiation workers engaged in nuclear medicine had significantly higher personal doses than other occupational categories,the differences were statistically significant(P<0.05).At the same time,this study also found that the abnormal rate of abdominal ultrasound in radiation workers engaged in interventional medicine was 42.31%,far higher than the average level of 31.13%.The abnormal detection rate of blood pressure and abdominal ultrasound in nuclear medicine majors was significantly higher than that in other occupational categories(P<0.05).Conclusion In the past three years,interventional medicine received the highest radiation dose among radiation workers,with a relatively high distribution range of effective doses,while nuclear medicine had the highest per capita annual effective dose.At the same time,the abnormal rate of abdominal ultrasound in interventional medicine is much higher than the average level,while in nuclear medicine,the abnormal detection rate of items such as blood pressure and abdominal ultrasound is significantly higher than other occupational categories.
