Herein lies the true advantage of the radiocarbon method, it is able to be uniformly applied throughout the world.
Included below is an impressive list of some of the types of carbonaceous samples that have been commonly radiocarbon dated in the years since the inception of the method: The historical perspective on the development of radiocarbon dating is well outlined in Taylor's (1987) book "Radiocarbon Dating: An archaeological perspective".
14C also enters the Earth's oceans in an atmospheric exchange and as dissolved carbonate (the entire 14C inventory is termed the carbon exchange reservoir (Aitken, 1990)).
Plants and animals which utilise carbon in biological foodchains take up 14C during their lifetimes.
As 14C decays it emits a weak beta particle (b ), or electron, which possesses an average energy of 160ke V.
Oakley (1979) suggested its development meant an almost complete re-writing of the evolution and cultural emergence of the human species.They exist in equilibrium with the C14 concentration of the atmosphere, that is, the numbers of C14 atoms and non-radioactive carbon atoms stays approximately the same over time.As soon as a plant or animal dies, they cease the metabolic function of carbon uptake; there is no replenishment of radioactive carbon, only decay.Libby later received the Nobel Prize in Chemistry in 1960: (From Taylor, 1987).Today, there are over 130 radiocarbon dating laboratories around the world producing radiocarbon assays for the scientific community.
