TITLE AUTORADIOGRAM MARKING PROCESS ABSTRACT OF THE DISCLOSURE A process of forming indicia on autoradi- ograms is disclosed wherein a substrate containing a distribution of radioactive material, such as radio- actively tagged proteins, is marked with a hexagonal Wurtzite form of zinc sulfide doped with trace metals phosphor. The thusly marked substrate is exposed to actinic radiation to charge the phosphor. The sub- strate is then superposed on an X-ray film to form a latent photographic image in the film which is developed by conventional means to form a photo- graphic image of the phosphorescent indicia and the distribution of radioactive matrial in the substrate.
