1. A known amount of a radioactive substance added to an experiment usually to trace (with a geiger counter or similar equipment) the movement of the non-radioactive component of that element through the experiment. 2.A known amount of an enriched stable isotope added to an experiment usually to determine the amount of the non-tracer component of that element using a mass spectrometer. Such tracers have important uses in medicine, geology, biology and chemistry.

A distinguishable substance, usually radioactive, administered to determine the distribution and/or metabolism of materials in the body. In 1923, George Hevesy was the first investigator to use an isotope (radioactive thorium) in metabolic studies, exploring lead transport in the bean plant. Metabolic studies proliferated after World War II, when with the development of the cyclotron, radioisotopes of various atoms became more widely available. ...
