Tritium as a tracer

http://www-naweb.iaea.org/napc/ih/TEU-tutorial/overview.html WebTritium is an example of a radioactive isotope. The principle behind the use of radioactive tracers is that an atom in a chemical compound is replaced by another atom, of the same chemical element. The substituting atom, however, is a radioactive isotope. This process is often called radioactive labeling.
