Carbon dating formula half life
The reaction is: (Where n is a neutron and p is a proton).The 14C formed is rapidly oxidised to 14CO2 and enters the earth's plant and animal lifeways through photosynthesis and the food chain.Plants and animals which utilise carbon in biological foodchains take up 14C during their lifetimes.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.
It is incorporated into plants through photosynthesis, and then into animals when they consume plants.
Today, there are over 130 radiocarbon dating laboratories around the world producing radiocarbon assays for the scientific community.
The C14 technique has been and continues to be applied and used in many, many different fields including hydrology, atmospheric science, oceanography, geology, palaeoclimatology, archaeology and biomedicine.
Oakley (1979) suggested its development meant an almost complete re-writing of the evolution and cultural emergence of the human species.
Desmond Clark (1979) wrote that were it not for radiocarbon dating, "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation" (Clark, 1979:7).
