Radiocarbon dating
Carbon 14 is the isotope of carbon measured in radiocarbon dating.
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.
Radiocarbon dating was developed by Willard Libby in the 1940s. It revolutionized archaeology by allowing accurate dating of organic materials up to approximately 50,000 years old based on the decay of the isotope carbon-14. This method has been instrumental in dating archaeological sites, determining the age of ancient artifacts, and understanding the timeline of human evolution.
Radiocarbon dating measures the decay of carbon-14 to determine the age of organic materials up to about 50,000 years old, while thermoluminescence dating measures the trapped electrons in soil or pottery to date inorganic materials up to hundreds of thousands of years old. Radiocarbon dating is limited by the availability of organic material, while thermoluminescence dating is limited by the environment in which the artifacts were buried.

Radiocarbon dating is not typically used to determine the age of the Earth because it can only accurately date organic materials up to around 50,000 years old. Other dating methods, such as radiometric dating of rocks and minerals, are used to estimate the age of the Earth, around 4.5 billion years.
Radiocarbon dating is generally accurate for dating organic materials up to about 50,000 years old. However, factors such as sample contamination and calibration errors can affect the accuracy of the results. It is important to consider these limitations when interpreting radiocarbon dates.
Radiocarbon dating is only accurate for objects up to about 50,000 years old, as the amount of carbon-14 left in the sample becomes too small to measure accurately beyond that point. Beyond this age limit, other dating methods such as potassium-argon dating or luminescence dating may be used to determine the age of older objects.
Radiocarbon dating was developed by Willard Libby in 1949.
Radiocarbon dating is the method that uses a measure of decaying carbon-14 isotopes in organic materials to determine their age.
