How to do carbon dating at home
For example, every person is hit by about half a million cosmic rays every hour.
It is not uncommon for a cosmic ray to collide with an atom in the atmosphere, creating a secondary cosmic ray in the form of an energetic neutron, and for these energetic neutrons to collide with nitrogen atoms.
Libby received the Nobel Prize in Chemistry for his work in 1960.
Radiocarbon is not stable; over time radiocarbon atoms decay into nitrogen atoms.
Thus, the ratio of radiocarbon to stable carbon in a living plant is the same as the ratio of radiocarbon to stable carbon in the atmosphere at any given time.
Animals (and humans) get their carbon atoms primarily from what they eat (i.e., plants).
The foregoing article was primarily based on a discussion of radiocarbon dating found in The Biblical Chronologist Volume 5, Number 1.
Cosmic rays enter the earth's atmosphere in large numbers every day.
Animals and people eat plants and take in carbon-14 as well.
