That means if you took one pound of 100 percent carbon-14, in 5,730 years, you would only have half a pound left.
Carbon-14 is created in the upper atmosphere as nitrogen atoms are bombarded by cosmic radiation.
After death, the carbon-14 would begin to decay at the rate stated above. The accuracy of this method, however, relies on several faulty assumptions.
First, for carbon-14 dating to be accurate, one must assume the rate of decay of carbon-14 has remained constant over the years.
As with any radioactive isotope, carbon-14 decays over time.
The half-life of carbon 14 is approximate 5,730 years.
The second faulty assumption is that the rate of carbon-14 formation has remained constant over the years.
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.
