Detailed explanation-1: -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-2: -Density is the overall darkness (blackness) of an image. Contrast is the difference in lightness and darkness between areas on a radiograph.
Detailed explanation-3: -Dark films with loss of detail, amalgams and over-exposure of areas that are still transparent. The main cause of this error is that the films have too much exposure. To correct this, it is important that you reduce the configuration of the machine. We advise you not to confuse this error with fogged films.
Detailed explanation-4: -It is best not to store the unexposed film in the x-ray room. It is possible that the constant scatter radiation may expose the film. Exposure to excess heat or humidity. Both are capable of stimulating the silver halide emulsion to the point of allowing development.
