Carbon dating calibration curve
Renfrew (1973) called it 'the radiocarbon revolution' in describing its impact upon the human sciences.Oakley (1979) suggested its development meant an almost complete re-writing of the evolution and cultural emergence of the human species.
"Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.
We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].
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.
There are three principal isotopes of carbon which occur naturally - C12, C13 (both stable) and C14 (unstable or radioactive).
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.
As 14C decays it emits a weak beta particle (b ), or electron, which possesses an average energy of 160ke V.
The decay can be shown: Thus, the 14C decays back to 14N.
Nyerup's words illustrate poignantly the critical power and importance of dating; to order time.Tags: Adult Dating, affair dating, sex dating
