Carbon 14 is the isotope of carbon measured in radiocarbon dating.
Radiocarbon dating
The history of radiocarbon dating goes back to 1949, where it was introduced to the world by Willard Libby. Radiocarbon dating is technique that uses the decay of carbon-14 to estimate the age of organic material.

Carbon dating is used to measure the age of organic material from long ago.
Radiocarbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. Measurement of radiocarbon was originally done by beta-counting devices, which counted the amount of beta radiation emitted by decaying 14 C atoms in a sample.
Carbon dating is used to measure the age of organic material from long ago.
Radiocarbon dating is effective for material of an age up to around 45,000 years before present.
Archaeologists use radiocarbon dating to estimate the age of organic remains in archaeological sites.
Radiocarbon dating was developed by Willard Libby in 1949.
Radiocarbon dating cannot be used to determine the age of fossils or "of the earth" because these materials no longer have radiocarbon or have negligible amount of radiocarbon.
A specialist that dates radiocarbon
It is through measuring the amount of carbon-14 in an organic sample that we can find out how long ago the sample was part of a living orgainsm. Organic materials that have been preserved in some way can be dated using this technique, called radiocarbon dating. There are limits to how far back we can look with radiocarbon dating, but it is very helpful in a lot of cases were the age of the material goes back a few tens of thousands of years.
