| 目的 了解核医学科工作人员131I职业性内照射的基本情况。方法 使用ORTEC Detective-100型便携式高纯锗谱仪, 对南京市某医院核医学科36名工作人员, 开展了为期6个月的甲状腺器官计数内照射体外直接测量。对待积有效剂量进行了估算, 分析了内照射剂量的分布情况以及与岗位、外照射个人剂量的关系。结果 监测周期内共监测203人次, 监测结果中低于记录水平的占总监测人次的85.7%, 高于记录水平的监测结果中, 低于调查水平的占总监测人次的12.8%, 高于调查水平的占总监测人次的1.5%。内照射个人剂量最高值2.54 mSv, 最低值0.015 mSv, 中位数为0.094 mSv。结论 监测周期内监测结果高于记录水平的工作人员占总监测人次的14.3%, 在核素治疗工作环境中, 无论是医生、护士、技师还是其他相关工作人员, 其接受的内照射剂量并无显著差异。 |

| Objective To investigate the basic situation of occupational internal exposure to 131I among staff in the nuclear medicine department. Methods Direct in-vitro measurements of thyroid doses from internal exposure were conducted for six months on 36 staff members of a hospital's nuclear medicine department in Nanjing using the ORTEC Detective-100 portable high-purity germanium (HPGe) spectrometer. The cumulative effective doses were estimated, and the distribution of internal doses and their relationship with job type and external doses were analyzed. Results During the monitoring period, a total of 203 monitorings were made. Of the monitoring result, 85.7% were below the recording level. Of the result exceeding the recording level, 12.8% were below the investigation level, while 1.5% exceeded the investigation level. The highest personal internal dose during the monitoring period was 2.54 mSv, the lowest was 0.015 mSv, and the median was 0.094 mSv. Conclusions During the monitoring period, 14.3% of the monitored staff had result above the recorded levels. In the working environment of radionuclide treatment, there is no significant difference in the internal dose received between doctors, nurses, technicians, or other relevant personnel. |
