Carbon 14 radiometric dating used
It is produced in the stratosphere and troposphere through the bombardment of waves of cosmic radiation on the element nitrogen-14.Neutrons from the cosmic radiation release the proton in nitrogen-14 converting it into carbon-14.
Obviously, if half the C-14 decays in 5,730 years, and half more decays in another 5,730 years, by ten half-lives (57,300 years) there would be essentially no C-14 left.Since it would only take less than 50,000 years to reach equilibrium from a world with no C-14 at the start, this always seemed like a good assumption.That is until careful measurements revealed a significant disequalibrium. All the present C-14 would accumulate, at present rates of production and build up, in less than 30,000 years!(Hedman 2007)Counting atoms is no easy task; this is evident by how new of a technology radiometric dating actually is.The process is a complicated one and can only completed two ways.Perhaps no concept in science is as misunderstood as "carbon dating." Almost everyone thinks carbon dating speaks of millions or billions of years.
But, carbon dating can't be used to date either rocks or fossils.
A "Back to Genesis" way of thinking insists that the Flood of Noah's day would have removed a great deal of the world's carbon from the atmosphere and oceans, particularly as limestone (calcium ate) was precipitated.
Once the Flood processes ceased, C-14 began a slow build-up to equilibrium with C-12—a build-up not yet complete.
Carbon is such a common element but only a fraction of the carbon atoms are that of carbon-14.
The carbon would have to be separated from other isotopes as well, so that the readings were only being emitted by the carbon-14.
Thus, no one even considers using carbon dating for dates in this range.
