Anything that was once alive or that was produced by a living thing can be dated by using the radiocarbon method of dating.This method, which received widespread attention in connection with the Dead Sea Scrolls, relies on the fact that all living things take in carbon, some of which is very slightly radioactive. To hear some people tell it, scientists have nearly absolute confidence in the dating methods they use.Most of the carbon before the Flood would then be C-12.
Since carbon comes from the air, does the amount of carbon-14 in the air remain constant?
Much of the carbon in the air is C-12, but a small amount of it is C-14.
A nitrogen atom hit by one of these neutrons changes into a C-14 atom and ejects a protein.
If a moving neutron enters a nitrogen nucleus, a proton comes flying out, and the nitrogen atom is changed to an atom of C-14. The constancy of C-14 in our atmosphere depends on the cosmic rays coming into the atmosphere at the same rate.
The plant, animal and human will each have about the same ratio of C-14 to C-12 as does the air.
The next question is: Where did the air get its C-14?
When cosmic rays enter the atmosphere, they cause "scatter radiation," which consists of little particles called neutrons.
A moving neutron is a high-energy particle which performs an interesting task.
But that's not really how it is when scientists are working in their labs.
To understand how the C-14 clock works and what processes are involved, let us consider the egg-timer.
He would give his bone a "date" of 15,000 to 30,000 years because of the very low C-14.
