ABSTRACT:
The problem of sensing the presence of radiographic elements using infrared sensors that occurs when a radiographic element contains one or more very thin tabular grain emulsions a total silver coating coverage of less than 30 mg/dm.sup.2 is addressed by placing particles in one or more non-emulsion hydrophilic colloid layers. The particles are removable during rapid access processing, have a mean equivalent circular diameter of from 0.3 to 1.1 .mu.m, and have an index of refraction at the wavelength of the infrared radiation that differs from the index of refraction of the hydrophilic colloid by at least 0.2.
