The accuracy of radiocarbon dating napervilledating
Second, radiocarbon dating becomes more difficult, and less accurate, as the sample gets older.
The bodies of living things generally have concentrations of the isotope carbon-14, also known as radiocarbon, identical to concentrations in the atmosphere.
Likewise, different living things absorb or reject carbon-14 at different rates.
Nor can it tell if a much older spearhead was attached to a brand-new shaft.
Carbon dating is reliable within certain parameters but certainly not infallible.
