Radiocarbon dating is one of the best known archaeological dating techniques available to scientists, and the many people in the general public have at least heard of it. But there are many misconceptions about how radiocarbon works and how reliable a technique it is. Radiocarbon dating was invented in the s by the American chemist Willard F. Libby and a few of his students at the University of Chicago: in , he won a Nobel Prize in Chemistry for the invention. It was the first absolute scientific method ever invented: that is to say, the technique was the first to allow a researcher to determine how long ago an organic object died, whether it is in context or not.

Radiocarbon Dating - Reliable but Misunderstood
Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. It only takes a minute to sign up. I understand how carbon dating works, though I do not understand why it doesn't happen while a creature is living. Because while we are alive we still have carbon 14 in us, so shouldn't it work? There are plenty of good sources online explaining the principle behind radiocarbon dating.

How can scientists accurately date when stone tools were made, like those found at Lake Turkana in Kenya? Radiocarbon dating is widely used to date materials like charcoal from hearths and carbonate in snail shells, Dr. Kent said, but it is limited to about the last 50, years because of the short half-life of carbon
