   Radionuclide
   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.

    radionuclide
    An isotope of artificial or natural origin that exhibits radioactivity.Radionuclides serve as agents in nuclear medicine and genetic engineering, play a role in computer imaging for diagnosis and experiment, and account for a percentage of background radiation to which humans are exposed. In cancer therapy, radionuclides that localise to certain or ...

    Radionuclide
    A `radionuclide` is an atom with an unstable nucleus, which is a nucleus characterized by excess energy which is available to be imparted either to a newly-created radiation particle within the nucleus, or else to an atomic electron (see internal conversion) . The radionuclide, in this process, undergoes radioactive decay, and emits a gamma ray(s) and/or subatomic particles. These particles constitute ionizing radiation. Radionuclides may occur n...

    radionuclide
    A radioactive nuclear species or nuclide. Of the 1,700 or so known nuclides, about 1,400 are radioactive. These radionuclides try to achieve a more stable structure by the emission of one or more different kinds of particles, including alpha particles. beta particles, or gamma rays, in the process k...
