Abstract In this paper, a real-time, dynamic radiation dose exposure assessment method is presented based on point-kernel method and stylized computational human phantom, for workers in radioactive environment. The stylized computational phantom is built and transformed into a series of organ-monitoring-points, and the kerma rates free-in-air at organ-monitoring-points are calculated by the point-kernel method. Based on the exposure dose rates of organ-monitoring-points, the absorbed doses of key tissues and organs are calculated, and the effective doses absorbed by the virtual worker is measured during typical decommissioning activities. In addition, to improve the accuracy of result and optimize the proposed method, we account for the influence of protective suit and the human body self-shielding in the calculations. This results in optimized dose assessment method with capability for dynamic calculations of dose exposure for workers in radioactive environment.

基于点核法和人体模型的放射性环境照射剂量评估实时模拟

摘要 本文提出了一种基于点核法和程式化计算人体模型的实时、动态辐射剂量暴露评估方法，适用于放射性环境中的工作人员。构建风格化的计算模型并将其转化为一系列器官监测点，并通过点核法计算器官监测点的空气中自由比释动率。根据器官监测点的照射剂量率，计算关键组织和器官的吸收剂量，并在典型退役活动中测量虚拟工作人员吸收的有效剂量。此外，为了提高结果的准确性和优化所提出的方法，我们在计算中考虑了防护服和人体自屏蔽的影响。
