In 1960, Libby was awarded the Nobel Prize in chemistry for this work.

He demonstrated the accuracy of radiocarbon dating by accurately estimating the age of wood from a series of samples for which the age was known, including an ancient Egyptian royal barge dating from 1850 BCE.

Emilio Segrè asserted in his autobiography that Enrico Fermi suggested the concept to Libby at a seminar in Chicago that year.

The carbon-14 isotope would vanish from Earth's atmosphere in less than a million years were it not for the constant influx of cosmic rays interacting with molecules of nitrogen (NFigure 1: Diagram of the formation of carbon-14 (forward), the decay of carbon-14 (reverse).

Carbon-14 is constantly be generated in the atmosphere and cycled through the carbon and nitrogen cycles.

Carbon-14 is first formed when cosmic rays in the atmosphere allow for excess neutrons to be produced, which then react with Nitrogen to produce a constantly replenishing supply of carbon-14 to exchange with organisms.

Wiki Journal of Science is an open-access, free-to-publish, Wikipedia-integrated academic journal for science, mathematics, engineering and technology topics. The method was developed in the late 1940s by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960.

Thus, the Turin Shroud was made over a thousand years after the death of Jesus.

The technique of radiocarbon dating was developed by Willard Libby and his colleagues at the University of Chicago in 1949. Radiocarbon 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.
