Quantum mottle properties X-ray interactions are random events. Therefore, "uniform" x-ray exposure does not produce uniform film darkening. Regional variability in the film darkening is called "quantum mottle." Quantum mottle decreases as x-ray exposure is increased.

When radiographic film is exposed with fluorescent intensifying screens, the spatial x-ray quantum fluctuations are recorded on the film in the form of density fluctuations (“quantum mottle”). The x-ray quantum fluctuations can be regarded as the input and the quantum mottle as the output of the image-forming system.

Home, library, topics, volume i, r, radiographic mottle ... Quantum mottle is best seen when especially fast intensifying screens and/or when high energy (high kVp) X-rays are used. In these cases, more light photons are produced per X-ray photon, making it easier to see the individual X-ray quanta.

A 10% by weight tin (Z=50) loaded scintillating fiber screen increased the x-ray interaction efficiency to over 90% at x-ray energies used in mammography. Quantum mottle was more important than the secondary sources of noise due to the x-ray conversion processes in the x-ray detector.
