Sensitization of Anoxic Bacteria to X-rays by Di-t-butyl Nitroxide and Analogues

Since those that do include oxygen1 and nitric oxide2,3, both of which are stable free radicals, it was considered of interest to see if certain substituted nitroxides4, which are water-soluble stable free radicals, would exhibit similar properties.
