摘　　要：目的对2010—2011年南京军区放射工作人员个人剂量监测中数据异常的原因进行总结分析。方法采用个人剂量计,对个人剂量监测结果进行统计分析。结果 2010—2011年期间,全区共计125人次个人剂量异常,其中从事介入治疗工作的占57.6%,从事放射诊断工作的仅占2.4%。大部分异常剂量在5 mSv以下,且56.8%的剂量异常并非实际受照。导致剂量异常的原因主要有剂量计佩戴不规范(50.4%)、工作量大、接触射线时间长(37.6%),以及操作不规范(4.8%)等。结论加强防护知识培训,加大监督执法力度,提高个人防护意识,保证数据真实可靠,是下一步工作的重点。[Objective]To summarize and analyze the abnormal reasons of personal dose monitoring data among radiation workers in Nanjing military area command from 2010-2011.[Methods]By using personal dosimeter,the results of personal dose monitoring were analyzed statistically.[Results]During 2010-2011,a total of 125 person/times were detected for abnormal personal dose in Nanjing military area command.Among them,57.6% were people worked in department of interventional therapy,and only 2.4% worked in department of radiological diagnosis.Most of abnormal doses were less than 5mSv,and 56.8% of the abnormal doses were not caused by the actual exposure.The main reasons for abnormal doses included： the application of personal dosimeters was not standardized（50.4%）,the workload was heavy and the exposure time was too long（37.6%）,as well as the operation was not standard（4.8%）.[Conclusion]It is important to strengthen training of knowledge about radiation protection,enhance the intensity of law enforcement,improve the consciousness about personal radiation protection,and ensure that the data is reliable.
