Radio carbon dating accuracy
This carbon-14 dioxide then ends up in humans and other animals as it moves up the food chain. Libby introduced the carbon-14 dating method at the University of Chicago.
There is then a ratio of carbon-14 to carbon-12 in the bodies of plants, humans, and other animals that can fluctuate, but will be fixed at the time of death. The premise behind the method is to determine the ratio of carbon-14 left in organic matter, and by doing so, estimate how long ago death occurred by running the ratio backwards.
For every one trillion carbon-12 atoms, you will find one carbon-14 atoms.
The carbon-14 that results from the reaction caused by cosmic radiation quickly changes to carbon dioxide, just like normal carbon-12 would.
If you start with no carbon-14 in the atmosphere, it would take over 50,000 years for the amount being produced to reach equilibrium with the amount decaying.
One of the reasons we know that the earth is less than 50,000 years old is because of the biblical record.
There are a few reasons to believe this assumption is erroneous.
During the flood, subterranean water chambers that were under great pressure would have been breached.However, evidence indicates that the opposite is true.Experiments have been performed using the radioactive isotopes of uranium-238 and iron-57, and have shown that rates can and do vary.This would have resulted in an enormous amount of carbon-12 being released into the oceans and atmosphere.The effect would be not unlike opening a can of soda and having the carbon dioxide fizzing out.
As with any radioactive isotope, carbon-14 decays over time.
