C14 half life in years
WebJan 15, 2008 · The half-life of carbon-14 is only 5,730 years, so carbon-14 dating is only effective on samples that are less than 50,000 years old. Dinosaur bones, on the other hand, are millions of years old -- some fossils are billions of years old. To determine the ages of these specimens, scientists need an isotope with a very long half-life. WebApr 8, 2024 · Half the original quantity of carbon-14 will decay back to the stable element nitrogen-14 after only 5,730 years. (This 5,730 year period is called the half-life of radiocarbon, figure 5). 6 At this decay rate, hardly any carbon-14 atoms will remain after only 57,300 years (or ten half-lives).
