Sato, S. Iwai, S. Tanaka, T. Uehara, Y. Sakamoto, N. Yoshizawa, S. Furihata] A calculational method is presented to evaluate equivalent doses of tissues or organs and effective dose for high energy radiations, where the radiation weighting factor given in ICRP 60 was replaced by an average quality factor estimated from the Q-L relationship in ICRP 60. The equivalent doses of tissues or organs and fluence to effective dose conversion coefficients are calculated for photons up to 10 GeV with a Monte Carlo code EGS4 in which a mathematical model of an anthropomorphic phantom is included. The equivalent doses for 24 tissue and organs have been calculated for AP and PA incidence of aligned and expanded photons from 1 MeV to 10 GeV. The effective doses were obtained by summing the equivalent doses with tissue weighting factors from ICRP 60. It is also demonstrated that the kerma approximation overestimates significantly the effective dose for photons above 10 MeV.
