A radionuclide is an atom with an unstable nucleus that undergoes radioactive decay, emitting radiation in the form of alpha particles, beta particles, or gamma rays. These radioactive particles can be used for medical imaging, cancer treatment, and industrial applications.

The term radionuclide is one we apply to any atom with an unstable atomic nucleus. It's the correct term for radioisotope. These atoms are radioactive, and emit radioactivitywhen they undergo radioactive decay. There are unstable configurations of every element, and a few elements have no stable nuclear configurations at all. These include technetium, promethium, and also bismuth and all the elements with an atomic number greater than that of bismuth, which is 83.

Nuclear medicine scan?

For most nuclear imaging studies, radionuclide is injected into the patient and the images are taken with a gamma camera suspended above the patient who will be lying on a table. The camera detects the gamma rays emitted from the radionuclide in the patient's body and uses this information to produce an image that shows the distribution of the radionuclide within the body. The image is recorded on film and is called a radionuclide scan.
