At a very steady rate, unstable carbon gradually decays to carbon Radiocarbon dating, or simply carbon dating, is a technique that uses the Since its introduction it has been used to date many well-known Changes in the Earth's climate can affect the carbon flows between That is the true benefit of radiocarbon dating, that it can be employed anywhere in the world. Radiocarbon 14 C dating is an isotopic or nuclear decay method of inferring age for organic materials.

When news is announced on the discovery of an archaeological find, we often hear about how the age of the sample was determined using radiocarbon dating, otherwise simply known as carbon dating. Deemed the gold standard of archaeology, the method was developed in the late s and is based on the idea that radiocarbon carbon 14 is being constantly created in the atmosphere by cosmic rays which then combine with atmospheric oxygen to form CO2, which is then incorporated into plants during photosynthesis. When the plant or animal that consumed the foliage dies, it stops exchanging carbon with the environment and from there on in it is simply a case of measuring how much carbon 14 has been emitted, giving its age. But new research conducted by Cornell University could be about to throw the field of archaeology on its head with the claim that there could be a number of inaccuracies in commonly accepted carbon dating standards.
