One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains. With death, the uptake of carbon-14 stops. It takes 5,730 years for half the carbon-14 to change to nitrogen; this is the half-life of carbon-14.

Is carbon-14 an absolute dating technique?

Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms. Radiocarbon dating is essentially a method designed to measure residual radioactivity.

Is carbon dating absolute?

One of the most useful absolute dating methods for archaeologists is called radiocarbon dating. It works by measuring carbon isotopes, which are versions of the element carbon. All isotopes of carbon have 6 protons but different numbers of neutrons.

What type of dating is carbon-14?

radiocarbon dating Carbon-14 dating, also called radiocarbon dating, method of age determination that depends upon the decay to nitrogen of radiocarbon (carbon-14).
