radionuclide

Radioactive isotope, radioisotope Radiation physics A nuclide with an unstable neutron to proton ratio, which undergoes radioactive decay; an artificial or natural nuclide with an unstable nucleus, that decays spontaneously, emitting electrons–β-particles or protons–α-particles and γ-radiation, ultimately achieving nuclear stability; RNs are used as in vivo or in vitro labels, for RT, or as sources of energy

ra·di·o·nu·clide

(rā'dē-ō-nū'klīd)

An isotope of artificial or natural origin that exhibits radioactivity. Radionuclides are used in diagnostic imaging and cancer therapy.

Radionuclide

A chemical substance, called an isotope, that exhibits radioactivity. A gamma camera, used in nuclear medicine procedures, will pick up the radioactive signals as the substance gathers in an organ or tissue. They are sometimes referred to as tracers.
