Detailed explanation-1: -X-ray film is composed of a clear cellulose acetate film base that is coated with an emulsion of silver halide usually silver bromide grains suspended in a layer of gelatin. The emulsion with its protective cover is attached to the acetable base by an adhesive. The emulsion is sensitive to X-rays.
Detailed explanation-2: -X-ray film displays the radiographic image and consists of emulsion (single or double) of silver halide (silver bromide (AgBr) is most common) which when exposed to light, produces a silver ion (Ag+) and an electron. The electrons get attached to the sensitivity specks and attract the silver ion.
Detailed explanation-3: -The film’s emulsion layer contains silver halide crystals that capture the x-ray image.
Detailed explanation-4: -When X-ray photons [or light photons] strike the silver bromide crystals in the emulsion, minute amounts of silver ions are formed on the surface of the crystal and bromine is liberated and is absorbed by the gelatin.
Detailed explanation-5: –The rigid but flexible film base is coated on both sides with an emulsion consisting of silver halide crystals embedded in gelatin.
