Radioactive carbon dating calculations Talk dirty to girls chat sites
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.
Cosmic radiation striking the upper atmosphere converts about 21 pounds of nitrogen each year into radiocarbon (carbon-14).
Radiocarbon ages less than 3,500 years old are probably accurate.
Until recent years, scientists who believe in creation haven't had the necessary resources to explore radiometric dating in detail.
A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.
Plants take in carbon dioxide, incorporating in their tissues both carbon-14 (unstable) and normal carbon-12 (stable) in the same proportion as they occur in the atmosphere .
Carbon-14 then moves up the various food chains to enter animal tissueagain, in about the same ratio carbon-14 has with carbon-12 in the atmosphere.
Half of it will decay in about 5,730 years to form nitrogen.
