Abstract

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 {111} major faces, an average equivalent circular diameter of at least 0.5 µm and an average thickness of less than 0.30 µm, 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 µm2 of its grain surface and per (0.1 µm of thickness)2 ; and at least a sulfite salt in such an amount that the ratio of the number of gold atoms per µm2 and (concentration of said sulfite salt, expressed in mmole per mole of silver)2 is at least 200000.
