In general, the allowable amount is 1/100 of the material thickness up to a maximum of …
WebRadiographic Density. Radiographic density (AKA optical, photographic, or film density) is a measure of the degree of film darkening. Technically it should be called "transmitted density" when associated with transparent-base film since it is a measure of the light transmitted through the film.
