When a machine outside the body delivers it, it is called external-beam radiation therapy. If radioactive materials are placed inside the body, it is called internal radiation therapy, or brachytherapy. You can also receive an injection of radioactive iodine, which travels through the body to kill cancer cells, a treatment called systemic radiation therapy.
