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. Web30 aug. 2024 · The remaining isotopes of nitrogen are highly unstable and their half-lives are very short. Of the 16 radioisotopes of nitrogen, the longest-lived is nitrogen-13 (13 …
