radioactive isotope, also called radioisotope, radionuclide, or radioactive nuclide, any of several species of the same chemical element[1] with different masses whose nuclei are unstable and dissipate[2] excess energy by spontaneously emitting radiation[3] in the form of alpha[4], beta[5], and gamma rays[6].
A brief treatment of radioactive isotopes follows. For full treatment, see isotope: Radioactive isotopes[7].

isotope: Radioactive isotopes
[8]Every chemical element has one or more radioactive isotopes. For example, hydrogen[9], the lightest element, has three isotopes with mass numbers 1, 2, and 3. Only hydrogen-3 (tritium[10]), however, is a radioactive isotope[11], the other two being stable. More than 1,000 radioactive isot...
