Radioactive decay dating formula

It may be used to date a wide range of natural and man-made materials.Fossils may be dated by taking samples of rocks from above and below the fossil's original position.

The decay may happen by emission of particles (usually electrons (beta decay), positrons or alpha particles) or by spontaneous nuclear fission, and electron capture.

The method works best if neither the parent nuclide nor the daughter product enters or leaves the material after its formation.

Anything which changes the relative amounts of the two isotopes (original and daughter) must be noted, and avoided if possible.

This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.

After 5,730 years, the amount of carbon 14 left in the body is half of the original amount.
