Define radio carbon dating

Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine.Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms.Over the years, other secondary radiocarbon standards have been made.

Archaeology and other human sciences use radiocarbon dating to prove or disprove theories.

Carbon 14 is continually being created in the Earth's atmosphere by the interaction of nitrogen and gamma rays from outer space.

Since atmospheric carbon 14 arises at about the same rate that the atom decays, the Earth's levels of carbon 14 have remained constant.

So by measuring carbon 14 levels in an organism that died long ago, researchers can figure out when it died.

The procedure of radiocarbon dating can be used for remains that are up to 50,000 years old.16 feet under: finding a matched set of whitetail sheds can be tough enough when they're lying on top of the ground.
