How Does Radiocarbon-14 Dating Work?
What is Radiometric Dating - Radioactive Dating - Definition
Despite the name, it does not give an absolute date of organic material - but an approximate age, usually within a range of a few years either way. There are three carbon isotopes that occur as part of the Earth's natural processes; these are carbon, carbon and carbon 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. The other two isotopes in comparison are more common than carbon in the atmosphere but increase with the burning of fossil fuels making them less reliable for study 2 ; carbon also increases, but its relative rarity means its increase is negligible. The half-life of the 14 C isotope is 5, years, adjusted from 5, years originally calculated in the s; the upper limit of dating is in the region of , years, after which the amount of 14 C is negligible 3.

Radio carbon method - definition of Radio carbon method by The Free Dictionary https: Related to Radio carbon method: Radioactive carbon dating , C14 dating. A form of radiometric dating used to determine the age of organic remains in ancient objects, such as archaeological specimens, on the basis of the half-life of carbon and a comparison between the ratio of carbon to carbon in a sample of the remains to the known ratio in living organisms. Also called carbon dating , carbon dating.
Radiometric dating or radioactive dating is any technique used to date organic and also inorganic materials from a process involving radioactive decay. 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. All these methods are based on the fact the rate at which radioactive nuclei disintegrate is unaffected by their environment, it can be used to estimate the age of any material sample or object which contains a radioactive isotope. Calculations of the decay of radioactive nuclei are relatively straightforward, owing to the fact that there is only one fundamental law governing all decay process. The radioactive decay law states that the probability per unit time that a nucleus will decay is a constant, independent of time.
