Year libby discovered radiocarbon dating
Plants take up atmospheric carbon dioxide by photosynthesis, and are ingested by animals, so every living thing is constantly exchanging carbon-14 with its environment as long as it lives.
Once it dies, however, this exchange stops, and the amount of carbon-14 gradually decreases through radioactive beta decay with a half-life of 5,730±40 years.
The technique of radiocarbon dating was developed by Willard Libby and his colleagues at the University of Chicago in 1949.
After plants die or they are consumed by other organisms (for example, by humans or other animals) the C allows the age of the sample to be estimated.Most radiocarbon dating labs have liquid scintillation counters for radiometric dating and accelerator mass spectrometers for AMS dating.The history of radiocarbon dating goes back to 1949, where it was introduced to the world by Willard Libby.Radiocarbon dating is an radioactive isotope dating technique used in dating materials which contain the unstable carbon-14 isotope.Radiocarbon dating is used to determine the age of previously living organisms.
