WebFor example, knowing that the half-time of carbon-14 is about 5730 years (t 1/2 = 5,730 years), and knowing that it is constantly produced in the atmosphere and consequently … WebCarbon-14 is a radioactive isotope with a half-life of approximately 5,730 years. This means that after 5,730 years, half of the original carbon-14 has decayed into nitrogen-14. This makes it a relatively short-lived isotope and therefore not suitable for dating events that occurred millions of years ago, such as those in the Pliocene epoch.
