Annual Review of Nuclear Science. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. This makes carbon an ideal dating method to date the age of bones or the remains of an organism. Deep time Geological history of Earth Geological time units. This is well-established for most isotopic systems.

Published by Gillian Floyd Modified over 3 years ago. After one half-life has elapsed, one half of the atoms of the nuclide in question will have decayed into a "daughter" nuclide or decay product. There are a couple catches, of course. Stimulating these mineral grains using either light optically stimulated luminescence or infrared stimulated luminescence dating or heat thermoluminescence dating causes a luminescence signal to be emitted as the stored unstable electron energy is released, the intensity of which varies depending on the amount of radiation absorbed during burial and specific properties of the mineral. Carbon 14 occurs naturally, and is absorbed by all living things when we eat and drink. Archived from the original on 31 March
