One of the most frequent uses of radiocarbon dating is to estimate the age of organic remains from archaeological sites.

Carbon dating, also known as radiocarbon dating, is a method of estimating the age of carbon-bearing materials up to 60,000 years old.

Carbon dating was such an important discovery that American scientist Willard Libby won the top science award called the Nobel Prize for discovering it.

Do you know what you have in common with a tree and a dog? Carbon is an element that is found in every living thing on planet Earth. One form of carbon inside living things is called carbon-14.

The amount of carbon-14 gradually decreases through radioactive beta decay with a half-life of 5,730 years.

So, scientists can estimate the age of the fossil by looking at the level of decay in its radioactive carbon.

For the most accurate work, variations are compensated by means of calibration curves.

The method was developed by Willard Libby and his colleagues at the University of Chicago in 1949.

The relatively short-lived C taken into organic matter is also slightly variable. However, under about 20,000 years the results can be compared with dendrochronology, based on tree rings.Carbon-14 is a radioactive form of carbon, which sounds scary, but it's not dangerous, it just means that it's not stable, so after an organism dies, carbon-14 decays or goes away.Scientists know how fast carbon-14 decays, so by measuring how much of it is remaining in a dead organism, they can figure out how long it has been dead.Carbon is an element that is found in every living thing on planet Earth.A type of carbon called carbon-14 decays after an organism dies, so by measuring how much of it is remaining in a dead organism, scientists can figure out how old the organism is. We have over 95 college courses that prepare you to earn credit by exam that is accepted by over 2,000 colleges and universities.Carbon dating only works for fossils that are less than 60,000 years old, so carbon dating won't work if you find a dinosaur bone because dinosaurs lived on Earth millions of years ago.
