Ultraviolet (UV) radiation is a form of electromagnetic radiation. Higher energy UV rays often have enough energy to remove an electron from (ionize) an atom or molecule, making them a form of ionizing radiation. Ionizing radiation can damage DNA in the cells in our body, which in turn may lead to cancer. But because UV rays don’t have enough energy to penetrate deeply into the body, their main effect is on the skin.
