X-rays generally have high energy and a high frequency.

Explanation:

High-energy X-rays or HEX-rays are very hard X-rays, with typical energies of 80–1000  keV (1 MeV), about one order of magnitude higher than conventional X-rays (and well into gamma-ray energies over 120 keV).

Radio waves have much longer wavelengths and lower frequencies than do visible light waves. In contrast, X-rays have much shorter wavelengths and higher frequencies. Likewise, red light has a longer wavelength than blue light. We can also think of light as consisting of particles or packets on information that we call photons.
