So, the fossil is 8,680 years old, meaning the living organism died 8,680 years ago. If the fossil has 35% of its carbon 14 still, then we can substitute values into our equation. Where t 1/2 is the half-life of the isotope carbon 14, t is the age of the fossil (or the date of death) and ln() is the natural logarithm function. We can use a formula for carbon 14 dating to find the answer. When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is –0.693.įor example, say a fossil is found that has 35% carbon 14 compared to the living sample.

After 5,730 years, the amount of carbon 14 left in the body is half of the original amount. The Ice Princess Magic Mirror makes role play even more fantastical with magical sounds and glowing lights (3 AA batteries required, not included). This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago. In the case of radiocarbon dating, the half-life of carbon 14 is 5,730 years. The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay. Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers. Experts can compare the ratio of carbon 12 to carbon 14 in dead material to the ratio when the organism was alive to estimate the date of its death. When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon 14. At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues. Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles.
