Detailed explanation-1: -hydrochloric acid (5ml), water (200ml) mixed in an old tea cup or beaker. This solution has very long shelf life. To lighten a dark radiograph it is soaked in water to make it soft, it is then rinsed in the reducing solution until the required density is obtained, washed, fixed and then dried.
Detailed explanation-2: -Fixing solution is used in the darkroom to fix (i.e. remove unexposed silver) the developed and rinsed x-ray film in conventional radiography.
Detailed explanation-3: -Stray radiation reaching the film either as a result of background fog, or owing to scatter from within the patient, produces unwanted film density (blackening), and thus reduces radiographic contrast.
Detailed explanation-4: -PROCESSING THE EXPOSED FILM The developer solution is the first solution into which the films are placed. The developer chemically reduces the energized ionized silver bromide crystals by donating electrons, removing the halides and precipitating metallic silver in the emulsion layer.
