Abstract

Abstract: 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 a 16 N 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%. Highlights: The results of an EURADOS comparison on the usage of the ICRP Reference Computational Phantoms are summarized and discussed. A scenario of immersion in a 16 N beta source cloud confined within a concrete wall room has been considered. Mistakes commonly made when implementing the phantoms for Monte Carlo simulations have been identified and corrected. Participants in the comparison finally succeeded to calculate HT within a ±5% agreement with the reference values.
