Submissivewomenchat - Application of carbon dating
The radiocarbon dating method is based on certain assumptions on the global concentration of carbon 14 at any given time.One assumption is that the global levels of carbon 14 (also called radiocarbon) in the atmosphere has not changed over time.
The carbon 14 produced reacts with oxygen atoms in the atmosphere to form carbon dioxide.
This carbon dioxide is no different from those produced by carbon 12 and carbon 13; hence, carbon dioxide with carbon 14 has the same fate as those produced with the other carbon isotopes.
Mixing and exchanges happen between the atmosphere and the biosphere until such time that equilibrium is established.
Radiocarbon dating rests heavily on this assumption such that other sources of carbon 14 had, at first, not been considered nor accounted for.
Nowadays, radiocarbon scientists had to perform calibration not only to convert their radiocarbon year results into calendar year but also to take into account the various factors that have major effects on the global levels of carbon 14, one of which is nuclear weapons testing.
