Antioxidants and Survival Time of Mice Exposed to Multiple Sublethal Doses of X-Irradiation.

Abstract
Experiments were conducted to determine the effects of antioxidants on the survival time of mice exposed to multiple sublethal doses of total body X-irradiation. Mixed tocopherols and Santoquin at a 0.25% level in the diet, and DPPD at levels of 0.25% or 0.5% of the diet had little if any protective effect. Propyl gallate, DBH and BHT at levels of 0.25% or 0.5% of the diet increased survival over that on the basal unsupplemented ration.
