| 目的 探讨尿钚放化分离结合α谱分析的监测方法作为职业人员吸入钚所致内照射个人剂量监测的适宜性，为核工业职业卫生管理和钚设施单位开展尿钚监测提供参考。方法 以美国能源局（DOE）核设施单位的钚化合物组成为例，使用模拟计算的方法，分别推导了急性和慢性吸入钚化合物致个人有效剂量分别为1 mSv时的尿钚水平，并与放化分离后α谱分析的典型探测限进行比较，分析尿钚监测用于个人剂量估算的适用性。结果 仅对于吸入M类钚化合物后10 d内使用放化分离α谱分析进行尿钚监测可以满足1 mSv探测限要求。结论 制定人员尿钚内照射个人剂量监测计划，须考虑监测方法的探测限，必要时通过工作场所监测结合受照时间等对工作人员的职业受照进行评价。 |

| Objective To explore the applicable conditions for using urine plutonium monitoring data to assess personal internal doses, in order to provide references for the occupational health management and the urine plutonium monitoring in nuclear sector. Methods Using some plutonium mixtures from DOE nuclear facilities, as an example, the urine plutonium levels were estimated through simulation calculation at 1 mSv effective dose arising from either acute or chronic inhalation of plutonium compounds, respectively. The results were compared with the typical detection limit of radiochemical separation and α-spectrometry. The feasibility of urine plutonium monitoring for dose assessment of internal radiation exposure was discussed. Results Only for type M plutonium compunds, 1 mSv detection limit can be achieved using radiochemical separation and α-spectrometry within 10 d after inhalation. Conclusions Before the monitoring plan of urine plutonium is made, detection limits of monitoring method should be considered. Internal dose could be accessed using workplace air monitoring and working hours when necessary. |
