Abstract
A process for reducing patient and personnel hazards from exposure to X-radiation during diagnostic procedures, comprising irradiating a photographic emulsion to produce an underexposed radiograph, developing and fixing the radiograph and treating the underexposed processed radiograph in a one-step copper ion image enhancement composition to intensify the image profile to a level at least equivalent to a fully exposed radiograph. The copper ion image enhancement composition enables a reduction in radiation exposure to patient and personnel up to 50% and more over what is generally regarded as the usual and permissible level of radiation for a given diagnostic radiographic examination.
