Radiocarbon dating how stuff works

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.

Libby and a few of his students at the University of Chicago: in 1960, he won a Nobel Prize in Chemistry for the invention.C-14 is produced in the upper atmosphere when nitrogen-14 (N-14) is altered through the effects of cosmic radiation bombardment (a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope).The new isotope is called "radiocarbon" because it is radioactive, though it is not Jonathan Du Hamel Age dating by measuring the amount of carbon-14 (C14) in a piece of wood and other organic artifacts is widely used in archaeology.The method is valuable for estimating the age of an object, but it is only an estimate.
