The main idea is bremsstrahlung radiation, produced when fast electrons are slowed as they pass near the strong electric field of nuclei in the x-ray target. In a mammography tube, electrons accelerate toward a heavy metal target (like tungsten), and as they approach nuclei they are decelerated and emit photons. This braking radiation creates a continuous spectrum that forms the majority of the mammography beam. There can also be characteristic radiation if inner-shell electrons are knocked out and higher-shell electrons fill the vacancy, yielding discrete-energy photons, but that contributes far less to the primary beam than bremsstrahlung. The other processes—Compton scattering and the photoelectric effect—describe interactions photons undergo in tissue or the target, not the primary production of the beam itself.
