Xrays and gamma rays are which type of radiation?

Explanation:
X-ray and gamma-ray photons have enough energy to remove electrons from atoms, which is the defining property of ionizing radiation. That ionizing capability means they can cause chemical changes and tissue damage, so they require shielding and exposure controls. In contrast, many other forms listed—such as lower-energy non-ionizing radiation—do not ionize atoms and interact with matter in different ways. Therefore, X-rays and gamma rays are classified as ionizing radiation.
