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

Very little radioactive material is needed in these diagnostic techniques because the radiation emitted is so easy to detect.

A tiny amount of carbon-14 is produced naturally in the upper reaches of the atmosphere, and living things incorporate some of it into their tissues, building up to a constant, albeit very low, level.

Once a living thing dies, it no longer acquires carbon-14; as time passes the carbon-14 that was in the tissues decays.

In another interesting example of radioactive dating, hydrogen-3 dating has been used to verify the stated vintages of some old fine wines.

One isotope, carbon-14, is particularly useful in determining the age of once-living artifacts.
