Question

what is x ray density?

Answer 1

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. Radiographic density is the logarithm of two measurements: the intensity of light incident on the film (I0) and the intensity of light transmitted through the film (It). This ratio is the inverse of transmittance.
