Radiocarbon dating - Wikipedia
WebRadiocarbon dating (also referred to as carbon dating or carbon-14 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.
What is Carbon Dating? | University of Chicago News
WebRadiocarbon dating, or carbon-14 dating, is a scientific method that can accurately determine the age of organic materials as old as approximately 60,000 years. First developed in the late 1940s at the University of Chicago by Willard Libby, the technique is based on the decay of the carbon-14 isotope.
How Carbon-14 Dating Works | HowStuffWorks
WebOct 20, 2023 · Key Takeaways. Carbon-14 dating works by comparing the ratio of carbon-12 to carbon-14 in a sample to that in a living organism, allowing for the determination of the age of formerly living things fairly precisely. The half-life of carbon-14 is 5,700 years, making it reliable for dating organic matter up to about 60,000 years old, with a ...

WebMar 8, 2024 · carbon-14 dating, method of age determination that depends upon the decay to nitrogen of radiocarbon (carbon-14). Carbon -14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere; the neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.
