The Carbon-14 Dioxide is then utilized by plants during their normal metabolism.
Animals and humans who eat these plants take the Carbon-14 into their systems just as they would Carbon-12 Dioxide.
Carbon-14 decays to a zero amount in 250,000 supposed years after its production.
It is incapable of yielding dates in the millions of years.
In high school biology courses they often teach about the inevitable failures of closed systems by taking an aquarium and placing snails, plants and a bowl of water inside; then sealing the aquarium so that no air may get in or out.
The Carbon-14 dating method was introduced by Dr. Libby (1908-1980) at the University of Chicago in 1949. Carbon-12 is the normal stable isotope of Carbon (99% of all Carbon), which is the basic building block of organic life forms.
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.
That means that starting with one pound of 100% Carbon-14, half of it would decay in 5,730 years, leaving 50%, or half a pound.
Then, in another 5,730 years, a second decay period would occur, leaving one quarter of a pound.

If this water vapor did exist in the past, then it would have effectively shielded the atmosphere from much of the cosmic radiation.
