There is then a ratio of Carbon-14 to Carbon-12 in the bodies of plants, animals and humans which could be considered as fixed at the time of death.After death, the Carbon-14 would decay and the ratio of the two isotopes would change.This bombardment causes a nuclear reaction to take place.The Carbon-14 produced by this process is then converted into carbon dioxide, just as normal Carbon-12 becomes carbon dioxide.There are more than 80 such technologies that are claimed to work.
These factors combine to cause fluctuations in the Carbon-12/Carbon-14 ratios found in plant, animal and human materials.
The process would continue, halving the amount left every 5,730 years until, theoretically, nothing remained of the original pound.
(approximately 78% of atmospheric gases) by thermal neutrons which come from the powerful cosmic radiation, primarily generated by the sun.
Besides the aforementioned items, the amount of cosmic radiation in the past, and in particular the amount reaching the atmosphere, may have been dramatically different.
If one were to believe the Bible, the earth was surrounded by a layer of water vapor between Creation and the Flood.
