Many people still cling to a different notion, despite the scientific evidence.

The radiation emitted by some radioactive substances can be used to kill microorganisms on a variety of foodstuffs, extending the shelf life of these products.

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

If half of the uranium has decayed, then the rock has an age of one half-life of uranium-235, or about 4.5 × 10 y.

One excellent example of this is the use of carbon-14 to determine the steps involved in photosynthesis in plants.

We know these steps because researchers followed the progress of carbon-14 throughout the process.

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.
