— Pre‐irradiation of stationary phase cells of Escherichia coli K‐12 with broadband near‐UV radiation potentiates the lethal effects of subsequent exposure to near‐UV radiation plus hydrogen peroxide. Identical fluences failed to modulate killing due to far‐UV radiation. These data indicate that biologically revelant levels of hydrogen peroxide may be generated in situ upon the near‐UV irradiation of cells.
