Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. Radiocarbon dating is based on the half-life of carbon isotope 14 (written as 14C) as it undergoes radioactive decay into the carbon about carbon dating method and radioactive isotopes 12 (12C). Radiometric dating is a method of dating based on the rate of decay of radioactive isotopes present in all organic materials.
