Web11 mei 2024 · This is why we look at the ratio between C14 and C12. If the atmosphere had a C14/C12 of 0.01%, then a C14/C12 of 0.005% means it died about 5,730 years ago. This is because carbon-14 decays into …
Web9 dec. 2010 · By about 58,000 years (ten half-lives) after an organism has died, there's so little radioactive carbon left (less than 1/1000) that calculations of age are no longer accurate. That's why radiocarbon dating is only reliable for samples up to 50,000 years old. But old age isn't the only thing that affects the accuracy of carbon dating. incoming webhook ms teamsWeb14 sep. 2024 · Carbon dating, also called radiocarbon dating, was discovered by Willard Frank Libby in the 1940s.
