在核设施停堆维修过程中,需要对维修工人受到的辐射剂量进行预评估。传统的评估方法是将人体简化为一个质点,无法精确评估不同器官的受照剂量。本文发展了一种基于包围盒策略的人体辐射剂量评估方法,并成功应用到国际热核聚变实验堆ITER极向场线圈维修工作人员辐射剂量评估中,结果表明,该方法不仅能提供更为精确的人体剂量评估结果,还能提供人体器官受照剂量,对考虑到器官剂量限值的工人作业方案制定有重要意义。 During the decommissioning of nuclear facilities, the radiation dose to maintenance workers needs to be pre-assessed. The traditional assessment method is to simplify the human body as a particle, can not accurately assess the dose of different organs dose. In this paper, a radiation dose assessment method based on the bounding box strategy is developed and applied to the radiation dose assessment of ITER polar field coil repair workers of ITER. The results show that this method can not only provide more accurate Human body dose assessment results, but also to provide human organ dose exposure, taking into account the limits of organ dosage workers work program formulation is of great significance.
