Summary:Disclosed is a method for the fabrication of an X-ray image intensifier tube. Before being introduced into the X-ray image intensifier, one of all the electrodes are entirely or partially covered with a layer of an orgainc polymer which is an electronic conductor of electricity and which has the property of reacting chemically with the alkaline metals deposited on the electrodes. Thus, the spurious illumination of the observation screen, due to the alkaline metals deposited on the electrodes during the preparation of the photocathode, is eliminated.
