title: Effect of primary and secondary radicals on chain breaks in ribosomal RNA in E. coli ribosomes.
abstract: Chain breaks in ribosomal RNA have been observed on gamma-radiation-induced inactivation of E. coli ribosomes. These breaks are caused by .OH and .H radicals, but not by e-aq and tertiary butanol-peroxy radicals.
