Two representative spur distances wrer introduced, one for an incident primary charged particle and one for a representative secondary electron, to calculate chemical yields among active species in a spur. The total yield from the track was a combination of these primary and secondary yields. Two coefficients of this combination were the parameters of the present model. Based on an optimization of these parameters by existing experimental Fricke G-values, the present model estimates the yield of OH at the microsecond timescaple after an irradiation, in aunified manner from electrons to heaby ions. The predicted yield of OH around the nano-second timescale afeter an irradiation may be a relevant baseis for a stydy on the mechanisms of radiation effects. This prediction by the present model was exemplified for electrons,photons and heavy ions( Proton,helium, carbon,neon,argon and iron).}, pages = {333--341}, title = {Estimation of Yields of OH Radicals in Water Irradiated by Ionizing Radiation}, volume = {46}, year = {2005} }
