How much radioactive material is used?
Nuclear medicine uses very small amounts of radioactive materials, or radiopharmaceuticals, to diagnose and treat disease. Radiopharmaceuticals are substances that are attracted to specific organs, bones, or tissues. When radiopharmaceuticals are introduced into the body, they produce emissions. A special type of camera, a gamma or PET camera, is used to transform these emissions into images and data which provide information about the area of the body being imaged.
