title: Induction of lethal damage in E. coli by Cerenkov emission associated with high-energy X-rays: the effect of bromouracil substitution.
abstract: 5.1. The damages induced in E. coli AB2487 recA by Cerenkov emission and ionizing radiation contribute in an additive fashion to the overall lethality, and do not interact in a synergistic fashion. 5.2. BU substitution enhances the lethal action of high energy X-irradiation on E. coli AB2487 recA by a mechanism involving enhanced radiosensitivity and enhanced photosensitivity.
