The AMS Laboratory was founded in 1981 by Professors Douglas J. Damon (Geosciences) with support from the National Science Foundation.Radiocarbon dating is a scientific analytical technique used for determining the age of samples which were once alive (eg. All organisms contain carbon, some of which is radioactive 14C, an isotope that is continuously being formed in the upper atmosphere.As living organisms take up radiocarbon along with other carbon atoms, the ratio between the two forms remains constant.There are exceptions to the theories and relationships introduced below that are beyond the scope of this discussion.

Carbon is the basis of life and is present in all living things.

Carbon-14 originates in the upper atmosphere of the earth and is created when neutrons originating from solar radiation bombardment collide with nitrogen in the air.
