Density definition x ray. The quantity of matter in a given space. Click image to align with top of page. Radiographic density aka optical photographic or film density is a measure of the degree of film darkening. The theoretical density is also known as x ray density because it requires information about the crystal structure of the studied compound which are deduced from x ray diffraction analysis.

The degree of film blackening in an area of a photograph or radiograph.

The ratio of the mass of a substance to its volume. 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.
