Due to their penetrating ability, hard X-rays are widely used to image the inside of objects (e.g., in medical radiography and airport security). X-ray from X-ray tubes is part of hi-energy electronic spectra of the anode material, so in reality the wavelength of most photons would be defined by anode material, and the only requirement for the potential difference is to be enough to cause excitation of the anode material.
