摘要
目的了解和掌握个人剂量监测工作情况,发现存在的问题,探索建立个人剂量监测的新模式,更好地对不同职业类型(放射诊断、放射治疗、核医学、介入治疗)的放射工作人员进行监督管理。方法选取天津市某三甲医院作为调查对象,整理分析了某三甲医院2010—2011年387人次个人剂量监测结果。结果某三甲医院的不同职业类型的放射工作人员中的介入治疗工作人员的人均年剂量当量最高,为0.58 mSv,为放射治疗的8倍之多。介入治疗工作人员个人剂量高于放射诊断、放射治疗以及核医学工作人员。结论应针对放射工作人员,尤其是介入治疗工作人员提出可行的加强放射防护的对策,为做好该市的个人剂量监测工作提供借鉴和指导。
[Objective]To understand and grasp the situation of individual dose monitoring,to identify gaps,and explore and create a new model for individual dose monitoring,so as to carry out management and supervision on radiation workers with different occupations（diagnostic radiology,radiotherapy,nuclear medicine,interventional treatment）.[Methods]A first-class hospital at Grade 3 was selected as study object,the monitoring results of 387 person-times from 2010-2011 were analyzed.[Results] The survey found that individual dose of workers engaged in interventional treatment（0.58 mSv） is highest among all radiation occupations and 8 times of radiotherapy,higher than those in diagnostic radiology,radiotherapy and nuclear medicine.[Conclusion]For radiation workers,especially the workers engaged in interventional therapy,the feasible countermeasures for radiological protection enhancement should be raised as the reference and guidance of individual dose monitoring in this city.
