This latter serves as a shield against all cosmic radiation - when its strength goes down, the bombardment increases, as does the number of carbon 14 atoms.
All living beings assimilate carbon dioxide molecules, a fixed but very small fraction of which contains carbon 14.
As a result, animal and plant life regularly assimilate carbon 14 atom together with the usual carbon 12.
Carbon has unique properties that are essential for life on Earth.Living organisms are constantly incorporating this C-14 into their bodies along with other carbon isotopes.When the organisms die, they stop incorporating new C-14, and the old C-14 starts to decay back into N-14 by emitting beta particles. These techniques are made possible by sensitive electronic instruments developed in the late twentieth century. A computer program for radiocarbon age calibration. Both methods rely on the ongoing production of radiocarbon in the upper atmosphere.
