Experiments were done to reduce the influence of unwanted X-ray exposures on Kodak Plus-X film. Variations of surface developer components showed no favorable results. The concentration of KBr was varied up to 10 grams per liter with again, no favorable results. The incorperation of benzitriazole decreased base plus fog from values of .81 to .56 with a significant decrease in speed. Phenyl mercaptotetrazole was extreamly effective in decreasing both base plus fog and speed.
