Carbon-14 dating is a revolutionary advancement in the study of the history of our planet.It is, in fact, leading to the “reconstruction of the history of the world”.There are three carbon isotopes that occur as part of the Earth's natural processes; these are carbon-12, carbon-13 and carbon-14.The unstable nature of carbon 14 (with a precise half-life that makes it easy to measure) means it is ideal as an absolute dating method.

This constant can be used to determine the approximate age of the decaying material through the ratio of radioactive isotopes to the estimated initial concentration of these isotopes at the time of the organism’s death.

The other two isotopes in comparison are more common than carbon-14 in the atmosphere but increase with the burning of fossil fuels making them less reliable for study (2); carbon-14 also increases, but its relative rarity means its increase is negligible. After this point, other Absolute Dating methods may be used.
