Radioactive isotopes are used to form images of the thyroid, bones, heart, liver, and many other organs. They used also have helped in treating diseased organs and tumors. The most commonly used example of such isotopes is technetium-99, which accounts for 80% of nuclear medicine procedures.he use of radioactive isotopes in medicine involves radionuclide therapy. Cancerous cells can be controlled or even eliminated by irradiating the tumor growth region. Teletherapy, also known as external irradiation is carried out by gamma beams emitted from radioactive cobalt-60 source.
The isotopes used are called radioactive tracers. Tracers are decaying atoms that have been mixed with high concentrations of other unstable atoms. Chemical reactants designed to seek out certain processes within the body are mixed in with the tracer atoms.adioactive decay can occur inside materials like rocks, and plants over long periods of time. It can also take place inside the human body. The importance of radioactive decay lies in the type of information that can gathered about a human body, or a fossil when radiation amounts are measured.
