ionizing radiation - (pronounced) (I-uh-NY-zing RAY-dee-AY-shun) A type of high-energy radiation that has enough energy to remove an electron (negative particle) from an atom or molecule to remove, causing it to become ionized. Ionizing radiation can cause chemical changes in cells and damage DNA. This can increase your risk of developing certain health conditions, such as cancer. Ionizing radiation can come from natural sources such as radon and cosmic rays (rays that enter the Earth's atmosphere from outer space). It can also come from medical imaging equipment such as X-ray, CT, or PET scan machines. Nuclear power plant accidents and nuclear weapons also release high levels of ionizing radiation. Exposure to very high doses of ionizing radiation can cause immediate harm to a person's body, including severe skin or tissue damage, acute radiation sickness, and death
