论文摘要
本文总结了从欧拉多斯工作组6的活动中组织的Bonner Spheres光谱法进行的国际比较练习获得的结果。考虑了四个现实的情况：一个医疗加速器，一个工作场所，辐照室和一个摩门西州的场景。提出了参考溶液，以理想化的通量能量分布和剂量速率以及使用经过验证的蒙特卡洛代码的衍生细节给出了参考溶液。然后，提供了参与者提交的各种不展开的结果，其中一些结果与参考解决方案非常吻合，而另一些则显示出明显的能源依赖性差异。最后，提出了对其中一些差异的解释，以及建议如何改善它们的建议方法。
This paper summarizes the results obtained from an international comparison exercise on neutron spectra unfolding in Bonner spheres spectrometry, organized within the activities of EURADOS working group 6: computational dosimetry. Four realistic situations were considered: a medical accelerator, a workplace field, an irradiation room and a skyshine scenario. The reference solutions are presented, given in terms of idealized fluence-energy distributions and dose rates, along with details of their derivation using verified Monte Carlo codes. The wide variety of unfolded results that were submitted by the participants are then provided, with some shown to agree well with the reference solutions but others showing significant energy-dependent discrepancies. Finally, explanations for some of these discrepancies are proposed, along with suggested methods for how they might be improved.
