EDIT: I want to add that carbon dating can only be somewhat accurate under the assumption that the levels of carbon in ...Nov 27, 2019 · Back when it was much stronger, it would have stymied carbon-14 production in the sky. Fewer carbon-14 atoms in plant and animal specimens (a lower carbon-14 ratio) would give them far more carbon years than they deserve. 2,3. When it comes to artifacts from the last 2,000–3,000 years, carbon dates generally match historical ages. Typically, the older the object, the less carbon-14 it contains as the radioactive isotope decays. The short half-life means that not enough carbon-14 is detectable after 55,000 years, and there should be none at all for 100,000 years or more. For these reasons, radiocarbon dating can never give dates of millions of years.Nature: Carbon dating uses the proportion of radioactive carbon-14 in organic material to determine a sample's age.
