Libby invented carbon dating for which he received the Nobel Prize in chemistry in 1960.The halflife of carbon 14 is 5730 ± 30 years, and the method of dating lies in trying to determine how much carbon 14 (the radioactive isotope of carbon) is present in the artifact and comparing it to levels currently present in the atmosphere.The carbon-14 undergoes radioactive decay once the plant or animal dies, and measuring the amount of carbon-14 in a sample conveys information about when the plant or animal died. Carbon dating has given archeologists a more accurate method by which they can determine the age of ancient artifacts.

If the fossil has 35% of its carbon 14 still, then we can substitute values into our equation.

One of the most well-known applications of half-life is carbon-14 dating.

The half-life of carbon-14 is approximately 5,730 years, and it can be reliably used to measure dates up to around 50,000 years ago.
