One way of artificially inducing nuclear transmutation is by bombarding stable isotopes with alpha particles.
Radioactive isotopes have many useful applications. In particular, they are central to the fields of nuclear medicine and radiotherapy.
Only hydrogen-3 (tritium), however, is a radioactive isotope; the other two are stable.
More than 1,800 radioactive isotopes of the various elements are known.
More than 1,000 radioactive isotopes of the various elements are known.
Approximately 50 of these are found in nature; the rest are produced artificially as the direct products of nuclear reactions or indirectly as the radioactive descendants of these products.cobalt-60 is extensively employed as a radiation source to arrest the development of cancer.
Radioactive isotope, also called radioisotope, radionuclide, or radioactive nuclide, any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, and gamma rays.
tritium), however, is a radioactive isotope, the other two being stable.

In nuclear medicine, tracer radioisotopes may be taken orally or be injected or inhaled into the body.
The radioisotope circulates through the body or is taken up only by certain tissues.
