title: [Effect of oxygen on gamma-radiation damage to nucleic acids irradiated in media with different pH values].
abstract: The injury to DNA and RNA exposed to gamma-radiation in media of varying acidity with oxygen present or absent therein has been investigated. The interaction of the protonated base with a superoxide radical has been shown to contribute markedly to the oxygen effect of the radiation injury to nucleic acids.
