目的调查我院核医学科工作场所的放射防护现状，依据辐射防护最优化原则制订有效的防护对策。方法对我院核医学科进行现场监测和调查，将监测的数据与国家标准进行比较。结果我院核医学科及其周围环境辐射最大值为0.51 μGy/h，科室的工作场所表面污染最大值为0.47 Bq/cm2，贮存敷贴器箱表面的韧致辐射空气比释动能率为2.31 μGy/h（5 cm）和0.23 μGy/h（100 cm），最大的年个人值为0.36 mSυ，无人员超过标准规定的照射剂量限值（5 mSυ）。结论检测结果符合相关标准的要求，我院核医学科具有较为完善的放射防护管理，在正常情况下能有效控制职业病的危害。

ObjectiveTo investigate the present situation of radiation protection in the workplace of nuclear medicine department of our hospital，and make effective protection measures according to the optimization principle of radiation protection. MethodsField monitoring and investigation were used in nuclear medicine department of our hospital, and the data were compared with the national standard. ResultsThe maximum value of nuclear medicine department and the surrounding environment was 0.51 μGy/h, the maximum value of the surface pollution in the workplace was 0.47 Bq/cm2, the surface of source storage’s air kerma rate were 2.31 μGy/h(5 cm) and 0.23 μGy/h(100 cm), the maximum value of personal dose was 0.36 mSυ, no one’s personal dose was more than the standard prescribed exposure dose limit(5 mSυ). ConclusionAll the measurement results meet the standard requirements, the management of radiation protection of nuclear medicine department of our hospital is relatively perfect completion, which can effectively control the occupational hazards.
