The determination of the age or date of organic matter from the relative proportions of the carbon isotopes carbon-12 and carbon-14 that it contains. The ratio between them changes as radioactive carbon-14 decays and is not replaced by exchange with the atmosphere.
- A highly sensitive method first developed for carbon dating, AMS quantifies isotopes with a detection limit of a few adducts in 10 nucleotides.
- We are waiting for the results of carbon dating and uranium isotope dating to give us more information about how old the skull is.
- Cassels says carbon dating, which always uses 1950 as the starting point, showed three main periods of hunting 100 years apart, going backwards in time from 450 years ago.
