The fluence to organ-dose and effective-dose conversion coefficients for neutrons and protons with energies up to 100 GeV were calculated using the PHITS code coupled to the male and female adult reference computational phantoms, which are to be released as a common ICRP/ICRU publication. For the calculation, the radiation and tissue weighting factors, wR and wT, as revised in ICRP Publication 103 were employed. The calculated data of these dose conversion coefficients are indispensable for constructing the radiation protection systems based on the new recommendations given in ICRP103 for aircrews and astronauts, as well as for workers in accelerators and nuclear facilities.
