A form of radiometric dating used to determine the age of organic remains in ancient objects, such as archaeological specimens, on the basis of the half-life of carbon-14 and a comparison between the ratio of carbon-12 to carbon-14 in a sample of the remains to the known ratio in living organisms. A technique for measuring the age of organic remains based on the rate of decay of carbon 14.

Libby estimated that the steady state radioactivity concentration of exchangeable carbon-14 would be about 14 disintegrations per minute (dpm) per gram carbon (ca 230 m Bq/g). Carbon-14 has a half-life of 5730 years and would have long ago vanished from Earth were it not for the unremitting cosmic ray impacts on nitrogen in the Earth's atmosphere, which forms more of the isotope. The New Zealand curve is representative for the Southern Hemisphere, the Austrian curve is representative for the Northern Hemisphere.

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.

Outside the range of recorded history, calibration of the 14 clock is not possible.

This means the above calculations are only evolution speculation and NOT backed up by real science.
