Carbon 14 bomb pulse dating
Nuclear weapons testing brought about a reaction that simulated atmospheric production of carbon 14 in unnatural quantities.
The huge thermal neutron flux produced by nuclear bombs reacted with nitrogen atoms present in the atmosphere to form carbon 14.
Radiocarbon scientists used this knowledge to test their theories regarding the mixing rates of carbon 14 through various carbon reservoirs.
They found out that tree rings do not exchange radiocarbon with other tree rings.
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.
Our bodies are prolific artists, creating new cells throughout the body.
According to literature, the excess carbon 14 produced during nuclear weapons testing has already decreased due in part to the global carbon exchange cycle.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.The carbon 14 produced is what is known as bomb carbon or artificial radiocarbon.According to literature, nuclear weapons testing in the 1950s and 1960s have nearly doubled the atmospheric carbon 14 content as measured in around 1965.
This fact has supported the use of dendrochronology in radiocarbon dating, particularly in constructing radiocarbon calibration curves.
