Radiocarbon dating lab
Plants and animals assimilate carbon 14 from carbon dioxide throughout their lifetimes.When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay.Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.
Learn about different types of radiometric dating, such as carbon dating.The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.No other scientific method has managed to revolutionize man’s understanding not only of his present but also of events that already happened thousands of years ago.Our AMS combustion lines were first built in 1996 by Dr.Tom Higham (now Oxford University) and our graphite lines started producing commercial AMS samples in 2002.
In this method, the sample is in liquid form and a scintillator is added.
