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.

The radiocarbon method is based on the rate of decay of the radioactive or unstable carbon isotope 14 (14C), which is formed in the upper atmosphere through the effect of cosmic ray neutrons upon nitrogen 14.

The reaction is: (Where n is a neutron and p is a proton).

Plants and animals which utilise carbon in biological foodchains take up 14C during their lifetimes.

Nyerup's words illustrate poignantly the critical power and importance of dating; to order time.

Radiocarbon dating has been one of the most significant discoveries in 20th century science.

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.
