Radiocarbon dating method synonyms
Its existence had been suggested by Franz Kurie in 1934.There are three naturally occurring isotopes of carbon on Earth: 99% of the carbon is carbon-12, 1% is carbon-13, and carbon-14 occurs in trace amounts, i.e., making up about 1 part per trillion of the carbon in the atmosphere. Carbon-14 decays into nitrogen-14 through beta decay.Carbon-14 has a relatively short half-life of 5,730 years, meaning that the amount of carbon-14 in a sample is halved over the course of 5,730 years due to radioactive decay.Carbon-14 would have long ago vanished from Earth were it not for the unremitting cosmic ray flux interactions with the Earth's atmosphere, which create more of the isotope.In living organisms, which are always taking in carbon, the levels of carbon 14 likewise stay constant.But in a dead organism, no new carbon is coming in, and its carbon 14 gradually begins to decay.
