REDUCTION OF THE EFFECTS OF NUCLEAR GAMMA RADIATION ON PHOTOGRAPHIC SILVER HALIDE EMULSIONS 1 January 1956 – 30 June 1958

摘要

The sensitivity of all photographic materials to nuclear radiation leaves little doubt that their usefulness in areas of high radiation levels, resulting from a nuclear explosion or from deliberate contamination with waste fission products, is seriously impaired. The present investigation was undertaken to evolve a photographic material or procedures, whereby acceptable ground or low altitude aerial reconnaissance photographs could be taken despite the existence of a high ambient level of gamma radiation.
