The comparative DRRs for exposure of canines to bilateral, uniform mixed neutron:gamma radiation relative to bilateral, uniform 1 Mev x-irradiation and Co-60 gamma irradiation. Canines, male/female, beagles or mongrels, were exposed to mixed neutron:gamma radiation at steady state dose rate for a bilateral, uniform exposure relative to the reference total-body irradiation at 9–40 rad min⁻¹ of Co-60 or 1 Mev x-radiation (Ainsworthet al. 1965; Earle et al. 1971; Norris et al. 1968; George et al. 1968; Macvittie and Jackson 2020).
