Calculation and benchmark of fluence-to-local skin equivalent dose coefficients for neutrons with FLUKA, MCNP, and GEANT4 Monte-Carlo codes

Abstract Dose equivalent limits for single organs are recommended by the ICRP (International Commission Radiological Protection publication 103). These do not lend themselves to be measured. They assessed convoluting conversion factors with particle fluences. The Fluence-to-Dose tabulated in literature. allow assessing organ dose of interest using numerical simulations. In particular, literature lacks knowledge local skin (LSD) coefficients neutrons. this article, we compute such values neutron energies ranging from 1 meV 15 MeV. We use FLUKA, MCNP and GEANT4 Radiation transport Monte-Carlo simulation codes perform calculations. A comparison between these three is performed. calculated important radiation protection studies radiotherapy applications.
