Abstract
G values (molecules per 100 eV) of the aqueous radiolytic products OH radical, HO2 radical, H2 and H2O2 molecules were measured for a variety of radiation types and scavenger concentrations. The radiations included 60Co gamma, protons, 4He, 14N and 20Ne ions. As expected G(OH) increased with increasing scavenger concentration and decreased with increasing LET (linear energy transfer, –dE/dx) of the radiation. G(H2) increased monotonically with increasing LET, as did G(HO2). G(H2O2) at first increased and then decreased with increasing LET. The results are compared with those of other workers and with computed G values from the modified prescribed diffusion model.Keywords
