ionizing radiation

high-energy particles or rays which can cause electrons to split off atoms. Certain types of ionizing radiation (such as x-rays) are used in medical tests to make pictures of what is inside the body. Larger doses of carefully controlled radiation are used in cancer treatment to kill cancer cells and shrink tumors. Exposure to ionizing radiation can also cause cancer. See also radiation, radiation dose, radiation therapy, x-ray.
