The ratio of carbon to carbon at the moment of death is the same as every other living thing, but the carbon decays and is not replaced. How a sample we can calculate the unequal one major it to give an example of carbon 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. Unstable nuclei decay. Despite the name, it does not give an absolute date of organic material - but an approximate age, usually within a range of a few years either way.
When we speak of the element Carbon, we most often refer to the most naturally abundant stable isotope 12 C.
Radiocarbon dating methods produce data that must then be further manipulated in order to calculate a resulting "radiocarbon age". Carbon is a radioactive isotope of carbon, containing 6 protons and 8 neutrons, that is present in the earth's atmosphere in extremely low concentrations.
