A radionuclide is a radioactive form of an atom that is either natural or manmade. They can be used in tiny amounts as a tracer in a bone scan, for example. Or they may be used as a cancer treatment. Iodine 131 is an example of a radionuclide - it is a radioactive form of iodine.Found on http://www.cancerhelp.org.uk/utilities/glossary/index.htm?search=r

An unstable form of a chemical element that releases radiation as it breaks down and becomes more stable. Radionuclides may occur in nature or be made in a laboratory. In medicine, they are used in imaging tests and in treatment. Also called radioisotope.Found on http://www.cancer.gov/dictionary?expand=R
A radionuclide or radioactive nuclide, also referred to as a radioisotope or radioactive isotope, is an atom with an unstable nucleus, characterized by excess energy available to be imparted either to a newly created radiation particle within the nucleus or via internal conversion. During this process, the radionuclide is said to undergo radioacti...Found on http://en.wikipedia.org/wiki/Radionuclide
