目的了解近年来福建省临床核医学放射工作人员的受照剂量水平,分析受照剂量超过调查水平的原因,为临床核医学放射防护提供基础数据。方法对2009-2011年福建省临床核医学放射工作人员进行个人剂量监测,并调查受照剂量超过调查水平人员的受照原因。结果 2009-2011年福建省临床核医学放射工作人员人均年剂量当量为0.64mSv·a-1。受照剂量超过每监测周期调查水平的有31人次,其中实际受照19人次,占调查人次数的61.2%。结论我省临床核医学工作人员人均受照剂量较低,但仍应注意加强用药后患者的管理、合理安排工作量,提高工作人员的防护意识。同时应进行手部剂量和内照射剂量的监测。
Objective To understand the dose levels of radiation workers in clinical nuclear medicine in Fujian Province in recent years and analyze the reasons why the doses exceeded the level of investigation so as to provide the basic data for clinical nuclear medicine radiological protection. Methods To monitor the personal radiation dose of clinical nuclear medicine radiologists from 2009 to 2011 in Fujian Province and investigate the causes of the exposure of those who received doses higher than the level of investigation. Results The per capita annual equivalent dose of radiation workers in clinical nuclear medicine in Fujian Province from 2009 to 2011 was 0.64mSv · a-1. There were 31 persons who took doses exceeding the level of investigation per monitoring cycle, of which 19 were actual, accounting for 61.2% of the number of investigators. Conclusions The per capita dose of clinical nuclear medicine staff in our province is relatively low. However, we should pay more attention to the management of patients after medication, arrange the workload reasonably, and raise the staff’s awareness of prevention. At the same time should be hand dose and internal radiation dose monitoring.
