The wavelength and the frequency have an inverse relationship. The shorter the wavelength of the wave, higher the frequency of the wave. Then the photon energy of the waves will be high because the energy of the photon is directly proportional to the frequency.
X-rays have a much shorter wavelength than radio waves. It carries more energy. It can ionize the matter. When it is incident on the biological material then it can disrupt the molecular bond.
This is the reason that an X-ray technician places a a lead cloth over parts of your body when taking an X-ray to protect your cells from being damaged.
