Abstract
The coliphage T7 was x-irradiated in the presence and absence of ethanol, an effective ·OH and ·H scavenger, in buffered suspensions saturated with N2, N2O and O2. In 10−3 × dilution of the original suspending organic medium, ethanol was protective in all three experimental conditions. In 10−5 × dilution of the original medium (equivalent to contaminant free), ethanol is also protective in all three experiments and to a greater extent; but the relative order of radiation sensitivities changes. It is concluded that, when irradiated in pure suspension, T7 phage is inactivated partly by ·OH, and that ·H and
