Implementation of ICRP116 Fluence to Effective Dose Conversion Coefficients in a FLUKA user routine

The estimation of the effective dose from the prompt radiation of a high energy and mixed radiation field is an important aspect of radiation protection at accelerator facilities. At present, it is possible to estimate effective dose from external irradiation with the FLUKA Monte Carlo code using conversion coefficients as suggested by ICRP Publication 74 and as calculated by M. Pelliccioni. This Technical Note describes the methodology with which the latest sets of conversion coefficients from the ICRP Publication 116 for neutrons, protons, charged pions, muons, photons, electrons and positrons have been implemented in a FLUKA user routine for converting fluence to effective dose for different external irradiation geometries during radiation transport. The conversion coefficients for several other particles, e.g. kaons and sigmas, are approximated by the conversion coefficients for particles having a similar radiological effect, as it has been done in the past.
