Iodine-131 has a half-life of only 8 d, so the potential for damage due to exposure is minimal.

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 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.
