[en] A model employing a spur overlap feature, an electron probability distribution which is displaced away from the center of the spur, and high and low spur density regions has been used to fit, within experimental error, hydrated electron decay data and the Fricke dosimeter G(Fe₃⁺) value from studies on the pulse radiolysis of pure water and aqueous solutions. The radiation source employed to obtain the pulse radiolysis electron decay data used in these studies was the Argonne 14 MeV Linac Accelerator. When the same model is used to predict yields from cobalt 60 gamma radiolysis experiments, there is quantitative agreement at low solute concentrations. At high solute concentrations, molecular product yields are not predicted as accurately. 5 figures
