Abstract
A process for the production of multiple radiographic images in which a corresponding number of photosensitive layers is exposed in a single shot to penetrating radiation and to photons emitted by fluorescent material sensitive to such penetrating radiation, characterized in that during such exposure each said photosensitive layer is located between a layer of said fluorescent material and a visible light reflecting layer which comprises white pigment particles and has a diffuse white light reflection density of less than 0.30.
