This work summarises the results of a comparison organized by EURADOS focused on the usage of the ICRP Reference Computational Phantoms. This activity aimed to provide training for the implementation of voxel phantoms in Monte Carlo radiation transport codes and the calculation of the dose equivalent in organs and the effective dose. This particular case describes a scenario of immersion in a¹⁶N beta source distributed in the air of a room with concrete walls where the phantom is located. Seven participants took part in the comparison of results using GEANT4, TRIPOLI-4 and MCNP family codes, and there was detected a general problem when calculating the dose to skeletal tissue and the remainder tissue. After a process of feedback with the participants the errors were corrected and the final results reached an agreement of ±5%.

这项工作总结了 EURADOS 组织的比较结果，重点是 ICRP 参考计算模型的使用。本次活动旨在为蒙特卡罗辐射传输代码中体素体模的实施以及器官剂量当量和有效剂量的计算提供培训。这个特殊案例描述了沉浸在¹⁶N β 源分布在幻影所在的混凝土墙房间的空气中。七名参与者参与了使用 GEANT4、TRIPOLI-4 和 MCNP 家族代码的结果比较，在计算骨骼组织和其余组织的剂量时发现了一个普遍问题。经过与参与者的反馈过程，错误得到纠正，最终结果达到±5%的一致性。
