Introduction:
A radioactive tracer is also called a radioactive label. It is a chemical compound in which an atom or more than one atom is replaced with a radionuclide. This is done so as to trace the path of the radioisotope and identify the mechanism of a chemical reaction by virtue of its radioactive decay.
