Coliphages of the strains Tl, T2, and T7 suspended in broth were inactivated by x rays. Under these conditions the phages Should be protected from indirect effects. The action of systeine and removal of oxygen were investigated. With T1, T2, and T7 hyperprotection by cysteine was found, which could not be substituted by anoxia. None of these phages showed a marked decrease in radiation sensitivity on removal of oxygen, whereas hyperprotection was strongly affected by air with T1 and T7 but not with T2. Tentative explanations for the differences between T1 and T2 were given. (auth)
