摘要
目的:了解三甲医疗机构放射工作人员职业外照射个人剂量监测状况,为优化放射防护工作管理提供指导。方法:选择我院从事放射工作人员,按不同岗位分为放射介入、核医学、放射治疗、放射影像诊断4组,使用热释光剂量仪和热释光元件对其进行个人剂量监测,比较其个人剂量。按不同职业将观察对象分为医师,护师,技师3组,比较其个人剂量。结果:放射工作人员年剂量当量水平低于国家标准限值。人均年剂量频数<5mSv,且人均年有效剂量有逐年下降趋势;各岗位年剂量值均数比较有统计学意义,其中放射介入最高,核医学次之,放射治疗、放射影像诊断无差异。医师和护师的人均年照射剂量高于技师(P<0.05)。结论:加强放射法规和防护知识培训,提高职业防护和职业健康管理意识,特别是加强介入放射学和核医学放射防护。
Objective To know personal radiodosimetry situation in radiology department in tertiaral hospital and provide protection guide. Method Staff in our hospital are divided into 4groups： interventional group, neuclide group, radiotherapy group and image group. Radiodosimetry will be done by thermoluminescent dosemeter. Every group is divided into phusician, nurse and thechniq subgroup and dosimetry result will be evaluated. Result Radiodosimetry shows radiation in radiology department is less than 5 msv, which is below the national standart, and trend goes down every year. There is significent difference in different group annually.radiation exposure dose is highest in interventional group,and neuclide group takes the second position. There is much difference in therapy group and image group.exposure dose is much higher in physician and nurse group than technique group.（P〈0.05） Conclusion Education law and knowledge, elevate the management awareness is inprotant.Protection in interventional group and neuclide group shoud be pay more attention.
