目的对2012-2014年期间北京部分军队医院放射工作人员个人剂量监测结果中出现的异常剂量进行总结分析。方法选取北京甲、乙、丙3家三甲军队医院的放射工作人员作为抽样调查对象,采用热释光剂量监测方法进行监测,将结果进行统计学分析。结果 2012-2014年共计监测4986人次,个人剂量出现异常31人次,异常剂量值主要集中在1.25~5 m Sv范围内,丙医院中出现异常剂量人次最多,共计19人次,占3家医院异常剂量总人次数的61.29%;不同工种情况中,出现异常剂量人次最多的是核医学工作人员,共计21人次,占异常剂量总人次数的67.74%。本次调查中,异常剂量产生主要原因包括工作量大、遗留在操作室,故意照射、佩戴位置不正确、操作中未佩戴个人防护用品5个方面。结论提高放射工作人员的防护意识,加强管理者对于放射防护工作的认识,科学利用监管手段,才能保证监测数据的真实性和准确性。
Objective To summarize the abnormal doses in the individual dose monitoring results of radiation workers in some military hospitals in Beijing during 2012-2014. Methods Radiological workers in three armored hospitals in Beijing A, B and C were selected as the sample survey subjects, and were monitored by thermoluminescence dose monitoring method. The results were statistically analyzed. Results A total of 4986 person-times were monitored in 2012-2014, with an abnormal dose of 31 individuals. The abnormal dose values mainly concentrated in the range of 1.25-5 mSv. In the C hospital, there were an abnormal dose of persons with the highest number of persons, accounting for 19 persons in total, accounting for 3 abnormal doses The total number of 61.29%; different types of occupations, the highest number of abnormal doses of nuclear medicine staff, a total of 21 people, accounting for 67.74% of the total number of people with abnormal doses. In this survey, the main causes of abnormal dose include heavy workload, left in the operating room, intentional exposure, wearing position is not correct, the operation did not wear personal protective equipment 5 aspects. Conclusion To improve the awareness of radiation workers to enhance their awareness of radiation protection work, scientific use of regulatory tools in order to ensure the authenticity of the monitoring data and accuracy.
