In 1960, Libby even went on to win Nobel Prize in Chemistry for this pathbreaking scientific method.Eventually, Libby was able to determine the age of an object upto 50,000 years with a precision of ± 10%.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.Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle: it is absorbed from the air by green plants and then passed on to animals through the food chain.The type of conversion that the people should employ depends on the technique applies.

Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.
Once the organism dies, however, it ceases to absorb carbon-14, so that the amount of the radiocarbon in its tissues steadily decreases.
Here are some interesting facts about carbon dating to note.
In the end of 1940s, Willard Libby developed the method of carbon dating.
