摘　　要：目的:分析个人剂量计检测结果,了解放射工作人员个人受量真实情况。方法:选择某医院2008-2010年从事放射或介入放射工作人员的个人剂量计检测结果,分析个人受量情况。结果:个人剂量超过50mSv 2008年1人,为核医学科人员,占当年检测人数的1.12%(1/89),2009年无1人,2010年3人,均为从事心内科介入手术人员,占当年检测人数的2.67%(3/112)。个人剂量超过20mSv但小于50mSv 2008年、2009年和2010年分别为2人、4人和4人,占当年检测人数的2.25%(2/89)、4.12%(4/97)和3.57%(4/112)。其中心内科9人,骨科1人。通过调查、现场检测和模拟实验,确认超过50mSv的4人中,核医学1人为周末下班后个人剂量计放在储源罐附近导致检测的数据失真,心内科3人为将个人剂量计佩戴之铅衣外侧导致数据失真。剔除失真数据后,2008年、2009年和2010年人年均受量情况分别为2.5mSv、3.5mSv和3.76mSv。结论:检测机构和管理部门通过加强辐射防护知识培训和监管方能确保数据的真实可靠,工作人员应提高工作的熟练程度减少射线的接触时间和合理的工作安排得到个人防护的目的。Objective：To study the real recived dose of the radiological workers by analysising the result of the personal dosimeter. Methods： Obtaining the personal dose by investigating the dose data of the workers who worked in the radiological department or involved in the radiological work in hospital during 2008 -2010. Results： A depart- ment of nuclear medicine personnel＇s dose was higher than 50mSv in 2008 ,accounted for 1.12% （1/89）. And there were 3 workers higher in amount in 2010, they were all Cardiac Department of Internal Medicine Operation personnel, accounted for 2.67% （3/112）. There were2 people in 2008,4 in 2009 ,and 4 in 2010 ,whose personal dose was high- er than 20mSv and less than 50mSv, respectively accounted for 2.25 % （2/89） ,4.12% （4/97） and 3.57% （4/112 ）.Nine worked in Cardiac Department of Internal Medicine, the other one was in the Department of Orthopedics. We en- sured that there were 4 distortions in the personal dose beyond 50mSv, testing and simulation experiment, as a matter of fact, a nuclear medicine put the personal dosimeter by the source - storage cans, and two Cardiac Department of In- ternal Medicine workers wear the personal dosimeter out of the lead clothing, making the data distorted. Ruled out the distortions ,the average of the personal dose were 2.5mSv,3.5mSv and 3.76mSv in 2008,2009 and 2010 respective- ly. Conclusion： Test organization and management department can make sure the data is reliable by strengthening the radiation protection knowledge training and regulatory, and also the involved workers should improve work proficiency to reduce the contact time or make a more reasonable work schedule to protect themselves.
