Abstract
Solutions of ferrous ammonium sulfate in 0.8N H2SO4 have been irradiated with Co60 gamma rays and with x‐rays from a 25‐Mev betatron. The energy absorbed per unit volume of solution has been calculated from a modification of the Bragg‐Gray formula, Ev=JvWρ in which the factor ρ was determined according to a calculated distribution of primary electron energies. The chemical yield was then calculated in terms of G, the number of ferrous ions oxidized per 100 ev absorbed.
