Radioactive isotopes are effective tracers because their radioactivity is easy to detect.A tracerA substance that can be used to follow the pathway of that substance through some structure. is a substance that can be used to follow the pathway of that substance through some structure.Recall that tritium, H, is a radioactive isotope of hydrogen.). Tracers can also be used to follow the steps of a complex chemical reaction. After incorporating radioactive atoms into reactant molecules, scientists can track where the atoms go by following their radioactivity.
