Dose conversion coefficients for ICRP110 voxel phantom in the Geant4 Monte Carlo code

•Monte Carlo codes Geant4 and VMC were used to simulate the ICRP110 male voxel phantom.•Geant4 was used to calculate organ Dose Conversion Coefficients for photons.•AP and PA irradiation geometries were simulated for benchmarking with the ICRP male phantom.•Geant4 results between 15 keV and 10 MeV present good agreement with published results.

The reference adult male voxel phantom recommended by International Commission on Radiological Protection no. 110 was implemented in the Geant4 Monte Carlo code. Geant4 was used to calculate Dose Conversion Coefficients (DCCs) expressed as dose deposited in organs per air kerma for photons, electrons and neutrons in the Annals of the ICRP. In this work the AP and PA irradiation geometries of the ICRP male phantom were simulated for the purpose of benchmarking the Geant4 code. Monoenergetic photons were simulated between 15 keV and 10 MeV and the results were compared with ICRP 110, the VMC Monte Carlo code and the literature data available, presenting a good agreement.
