WebScience. By the standard definitions of "x-ray" and "gamma ray", any photon produced by bremsstrahlung is by definition an x-ray and not a gamma ray. However, there's no upper bound to the photon energy that can be produced by bremsstrahlung. That's the neat part, gamma rays are just x-rays from nuclear interactions. fabia vrs uprated clutch
