Radioactive isotopes are effective tracers because their radioactivity is easy to detect.A is a substance that can be used to follow the pathway of that substance through some structure.For instance, leaks in underground water pipes can be discovered by running some tritium-containing water through the pipes and then using a Geiger counter to locate any radioactive tritium subsequently present in the ground around the pipes.(Recall that tritium 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.One excellent example of this is the use of carbon-14 to determine the steps involved in photosynthesis in plants.For example, if a thyroid tumor were detected, a much larger infusion (thousands of rem, as opposed to a diagnostic dose of less than 40 rem) of iodine-131 could help destroy the tumor cells.Similarly, radioactive strontium is used to not only detect but also ease the pain of bone cancers.
In another interesting example of radioactive dating, hydrogen-3 dating has been used to verify the stated vintages of some old fine wines.Very little radioactive material is needed in these diagnostic techniques because the radiation emitted is so easy to detect.
