Radiation weighting factors and conversion coefficients for high-energy radiation

In accordance with the list of actions decided at the SATIF-3 meeting, fluence-to-effective dose conversion coefficients for charged pions and kaons have been computed. Calculations have been carried out using the FLUKA Monte Carlo transport code, for various geometrical conditions of irradiation of an anthropomorphic computational model. The calculated results are given for twelve incident energies from 1 MeV to 10 TeV. In order to assign appropriate values to the radiation weighting factors in the high-energy region, several criteria have been analysed. Modifications of the recommended values are proposed for high-energy neutrons and protons and for charged pions. (author)
