摘　　要：目的分析单双剂量计评估方法在核医学外照射个人监测应用中存在的问题。方法采用问卷调查方法和现场个人剂量监测相结合的方法,依据GBZ128的要求,对全国10家医院52名核医学工作人员进行2个周期(每个周期2个月)的个人剂量监测。结果佩戴双剂量计的核医学工作人员,使用双剂量计方法估算的有效剂量值大多数小于铅衣内的剂量值;佩戴单剂量计的核医学工作人员,有效剂量的最大值为0.11 mSv;使用单剂量方法估算的有效剂量基本上都小于双剂量计方法估算的有效剂量。结论GBZ 128—2019《职业性外照射个人监测规范》给出的核医学人员单剂量计或双剂量计估算公式有待进一步完善。Objective To analyze the problems in the application of single and double dosimeter methods for monitoring personal dose of external radiationin nuclear medicine workers.Methods Both questionnaires and on-site personal dose monitoring were used to monitor the personal dose of 52 nuclear medicine workers in 10 hospitals in China according to GBZ 128 for two periods(for 2 months each period).Results Most of the effective doses calculated by the double dosimeter method were lower than the dosein lead clothing.For workers wearing the single dosimeter,the maximum effective dose was 0.11 mSv.The effective doses estimated by the single dosimeter method were generally lower than those estimated by the double dosimeter method.Conclusion The estimation formula of single or double dosimeter for nuclear medicine workers described in GBZ 128—2019(Specifications for individual monitoring of occupational external exposure)needs to be further improved.
