Radiocarbon Data & Calculations. In AMS, the filiamentous carbon or "graphite" derived from a sample is compressed into a small cavity in an aluminum "target" which acts as a cathode in the ion source. The surface of the graphite is sputtered with heated, ionized cesium and the ions produced are extracted and accelerated in the AMS system.

Why Is Radiocarbon Dating Important To Archaeology?

The radiocarbon dating method is based on certain assumptions on the global concentration of carbon 14 at any given time. One assumption is that the global levels of carbon 14 (also called radiocarbon) in the atmosphere has not changed over time. The other assumption is the corollary of the first; the biosphere has the same overall concentration of radiocarbon as the atmosphere due to equilibrium.
