目的了解福建省临床核医学工作人员个人剂量受照水平,为加强放射防护提供依据。方法收集2008—2011年临床核医学放射工作人员个人剂量检测结果并统计分析;对超过调查水平受照剂量者,分析具体原因。结果 2008—2011年全省设区市实测集体剂量当量为478.72mSv/人,人均年有效剂量为0.82mSv/a。个人年剂量<5mSv占监测总数的97.8%。超过调查水平剂量调查率84.2%(32/38),其中实际受照占50.0%。结论福建省临床核医学工作人员个人年均有效剂量处于低剂量水平,应科学安排工作量和工作时间,加强用药后病人管理,提高工作人员的防护意识,以减少辐射受照量。
Objective To understand the level of individual dose exposure of clinical nuclear medicine staff in Fujian Province and provide basis for enhancing radiation protection. Methods The results of individual dose testing of clinical nuclear medicine radiologists from 2008 to 2011 were collected and statistically analyzed. For those who exceeded the surveyed level, the specific reasons were analyzed. Results 2008-2011 municipalities set the city measured collective dose equivalent of 478.72mSv / person, the average annual effective dose of 0.82mSv / a. Individual annual dose <5mSv 97.8% of the total number of monitoring. Surveys 84.2% (32/38) of investigation level dose survey, of which 50% of the actual exposure. Conclusions The annual average effective dose of clinical nuclear medicine staff in Fujian Province is at a low dose level. The workload and working hours should be scientifically arranged to enhance the patient management after treatment and improve the staff’s awareness of protection so as to reduce the radiation exposure.
