目的探讨医院核医学科工作人员进行内照射监测的必要性。方法依据1999年IAEA推荐的标准,收集3家医院核医学科13名工作人员每年操作核素的种类、总活度及操作时所采取的防护措施等信息,判断工作人员是否需要进行内照射监测。结果除一名工作人员~(131)I给药的决定系数d值为0.6、总决定系数D值为6.03外,其余工作人员操作某种核素的决定系数d值和总决定系数D值均≥1。根据1999年IAEA推荐的判定标准,本次调查的工作人员均需要进行内照射监测。结论核医学科工作人员在进行核素的操作时存在发生内照射的风险,其职业活动中所受内照射剂量不容忽视,应加强核医学科的辐射防护,对核医学科工作人员进行常规的内照射监测。
Objective To investigate the necessity of internal radiation monitoring in hospital nuclear medicine department. Methods Based on the criteria recommended by the IAEA in 1999, we collected information on the types, total activities and protective measures taken by 13 workers in the nuclear medicine department of three hospitals each year to determine whether the staff needed internal monitoring . Results In addition to a staff member ~ (131) I d the decision-making coefficient of 0.6, the total determination coefficient D value of 6.03, the rest of the staff operating a nuclide determination coefficient d value and the total determination coefficient D value ≥1. According to the IAEA recommended criteria of 1999, all the staff in this survey need to carry out internal exposure monitoring. Conclusion There is a risk of internal irradiation during the operation of nuclide in nuclear medicine department. The dose of internal irradiation in its occupational activities should not be neglected. Radiation protection should be strengthened in nuclear medicine department. Internal exposure monitoring.
