Detailed explanation-1: -RADIOGRAPHIC DENSITY. Radiographic density is defined as the degree of blackness, or “darkness, ‘’ on a radiograph.
Detailed explanation-2: -The amount of darkness in the radiographic image reflects the radiographic density. It is called “transmitted density” in conventional film radiography because it measures the light transmitted through the film. In digital imaging, it refers to the shift of the histogram to the lower grey levels.
Detailed explanation-3: -Density is the degree of blackening on the film.
Detailed explanation-4: -Radiographic Density-the overall amount / degree of darkening on a radiograph. In routine radiography, the useful range of density varies from 0.3 to 2.0 density. The density below 0.3 is due to the density produced by the base and by some fog on the film (base plus fog).
