Abstract (en)

[origin: EP1195642A2] A direct X-ray radiographic element has been disclosed and a system for direct X-ray radiography comprised of said element, wherein said element is comprised of a support covered on at least one of its major faces with a tabular grain emulsion layer free from spectrally sensitizing dyes in which at least 50 percent of total grain projected area is accounted for by silver bromo(chloro)iodide tabular grains having an iodide content of at most 1 mole %, based on silver, having an average aspect ratio between 5 and 25, and having a volume between 0,05 and 2 mu m<3>, wherein a silver content per coded side, expressed as an equivalent amount of silver nitrate is between 5 and 25 g/m<2>, and further, being 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 10kVp, characterized in that said tabular grain emulsion(s) have selenium in an amount of 0.5to 20 mu mole of selenium per mole of silver nitrate.
