Radiocarbon dating is simply a measure of the level of C isotopes in the atmosphere can vary.

Today, the radiocarbon-14 dating method is used extensively in environmental sciences and in human sciences such as archaeology and anthropology.AMS counts the quantity of C isotope is constantly formed in the upper atmosphere thanks to the effects of cosmic rays on nitrogen-14 atoms.It is oxidised quickly and absorbed in great quantities by all living organisms - animal and plant, land and ocean dwelling alike.This allows researchers to account for variation by comparing the known records of C levels in the tree record, looking for a tree record that has the same proportion of radiocarbon.The overlapping nature of the tree records means this is the most accurate record we have.

AMS works slightly differently; it converts the atoms of the sample into fast-moving ions so that they become charged atoms.
