Abstract (en)
A system has been disclosed for use in radiographic industrial non-destructive testing materials and personal monitoring, making use therefor, of tabular silver brom(oiod)ide emulsion grains having ä111ü major faces, an average equivalent circular diameter of at least 0.5 mu m and an average thickness of less than 0.30 mu m, having been chemically sensitized by the steps of adding at least a gold salt in order to provide the surface of said tabular grains with at least 6000 atoms of gold per mu m<2> of its grain surface and per (0.1 mu m of thickness)<2> ; and at least a sulfite salt in such an amount that the ratio of the number of gold atoms per mu m<2> and (concentration of said sulfite salt, expressed in mmole per mole of silver)<2> is at least 200000.
