Photons fluence to local skin Dose coefficients and benchmark with three Monte-Carlo codes. Application to the computation of radioactive material transport limits

Fluence to Local Skin Dose Conversion Coefficients (LSD-CC) are radiological protection quantities used for external radiation exposures which allow the conversion of particle fluences into local skin equivalent dose. The International Commission on Radiological Protection published LSD-CC electrons with an energy range from 10 keV MeV. However, literature does not address these all types, in particular photons. In this article, computed values photons presented enrich and interest community. As example application use values, IAEA A1/A2 working group, supports review international regulation related transport radioactive material, has decided estimate dose using such coefficients. publication, benchmarked GEANT4, FLUKA MCNP. addition, Monte-Carlo calculation code is compute positrons compare existing data validate models. one transfer functions calculating A-values determined compared a one-step direct method.
