# Carbon 13 carbon dating scammer dating

14C is radioactive and has a half-life of 5730 years.

The half-life is the time taken for an amount of a radioactive isotope to decay to half its original value.

14C enters the dissolved inorganic carbon pool in the oceans, lakes and rivers.

The History of Radiocarbon Dating Willard Libby invented radiocarbon dating in the late 1940s.

His first publication showed the comparisons between known age samples and radiocarbon age (Libby et al, 1949; Libby, 1952). For the first time it was possible to obtain ages for many events which occurred over the past ~50,000 years.

This is called the half-life—the amount of time required for one-half of a given number of atoms to disintegrate. The plot of the number of tiles as a function of the number of turns looks like this: Again, I made radioactive spheres disappear when they decayed.

This is fine, because when carbon-14 decays, it produces nitrogen-14. But you could imagine that if you knew that the sample started with 20 percent blue spheres and you knew their half-life, then you could determine the age by examining one frame from the animation.

In 1960 Libby was awarded the Nobel Prize for chemistry for this contribution.
