I’ve taken the theory of Carbon Dating – that science reaches further with a little comedy – and applied it to live programming with a new 501(c)(3) called SCIENCE RIOT, INC.
Tom Higham (now Oxford University) and our graphite lines started producing commercial AMS samples in 2002.In 2007 Fiona Petchey visited the Keck Radiocarbon laboratory in Irvine, California and worked closely with Dr. Since 1980 we have run over 37000 radiometric and AMS samples. This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature.C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.It is naturally unstable and so it will spontaneously decay back into N-14 after a period of time.
It takes about 5,730 years for half of a sample of radiocarbon to decay back into nitrogen.
It takes another 5,730 for half of the remainder to decay, and then another 5,730 for half of what's left then to decay and so on.
The period of time that it takes for half of a sample to decay is called a "half-life." Radiocarbon oxidizes (that is, it combines with oxygen) and enters the biosphere through natural processes like breathing and eating.
Plants and animals naturally incorporate both the abundant C-12 isotope and the much rarer radiocarbon isotope into their tissues in about the same proportions as the two occur in the atmosphere during their lifetimes.
When a creature dies, it ceases to consume more radiocarbon while the C-14 already in its body continues to decay back into nitrogen.
