Autoradiogram marking process

A process of forming indicia on autoradiograms is disclosed wherein a substrate containing a distribution of radioactive material, such as radioactively tagged proteins, is marked with a hexagonal Wurtzite form of zinc sulfide doped with trace metals phosphor. The thusly marked substrate is exposed...

Zusammenfassung:	A process of forming indicia on autoradiograms is disclosed wherein a substrate containing a distribution of radioactive material, such as radioactively 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 substrate 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 photographic image of the phosphorescent indicia and the distribution of radioactive material in the substrate.
