In a dental X-ray tube, the incoming electrons are rapidly slowed as they pass near the nucleus of the target material, and that deceleration releases energy as photons. This braking radiation, known as general radiation, creates a broad, continuous spectrum of X-ray energies and tends to dominate the photon production because the high-speed electrons and high atomic number target (like tungsten) favor this process. Characteristic radiation, while it does occur when inner-shell electrons are ejected and higher-shell electrons fall to fill the vacancies, happens far less often and produces photons at specific energies, so its overall share is small. Scatter radiation arises from interactions of the produced X-rays with matter and is not the primary source of the beam. Therefore, the majority of dental X-ray photons come from general (bremsstrahlung) radiation.
