Is radio carbon dating flaws
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-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.
AMS works slightly differently; it converts the atoms of the sample into fast-moving ions so that they become charged atoms.By applying magnetic and electrical fields, the mass of these ions is measured and the accelerator is used to remove ions that might contaminate the dating.The sample passes through several accelerators in order to remove as many atoms as possible until the C pass into the detector.Very old trees such as North American Bristlecone Pine are ideal for constructing long and accurate records of the state of the atmosphere.This allows researchers to account for variation by comparing the known records of C levels in the tree record, looking for a tree record that has the same proportion of radiocarbon.
