Abstract
A system for industrial radiography is disclosed comprised of (1) an industrial radiographic element comprised of a support covered on each of its major faces with a tabular grain emulsion layer in which at least 50 percent of total grain projected area is accounted for by silver bromide tabular grains having an average aspect ratio of at least 2 and a volume greater than 0.03 .mu.m.sup.3 and (2) disposed on opposite sides of the radiographic element, two intensifying screens designed to emit electrons when exposed to X or gamma rays with an energy greater than or equal to 10 kV. A speed improvement is realized upon exposure and processing.

A system for industrial radiography comprised of (1) an X-ray sensitive radiographic element comprised of a support covered on each of its major faces with tabular grain emulsion layer in which at least 50 percent of total grain projected area is accounted for by silver bromide tabular grains containing at least 90 mol % bromide and having an average aspect ratio of at least 2 and a volume greater than 0.03 .mu.m.sup.3 and (2) disposed on opposite sides of the radiographic element, two intensifying metal screens designed to emit electrons when exposed to X or gamma rays with an energy greater than or equal to 10 kV.
A system for industrial radiography comprised of (1) an industrial radiographic element comprised of a support covered on each of its major faces with a tabular grain emulsion layer in which at least 50 percent of total grain projected area is accounted for by silver bromoiodide tabular grains having a uniformly distributed iodide content of less than 5 mole percent, based on silver, having an average aspect ratio of at least 2, and having a volume greater than 0.03 .mu.m.sup.3, and (2) disposed on opposite sides of the radiographic element, two intensifying screens designed to emit electrons when exposed to X or gamma rays with an energy greater than or equal to 10 kV.
