The variation is certainly partially the result of a change in the cosmic ray production rate of radiocarbon.
The cosmic-ray flux, and hence the production rate of C-14, is a function not only of the solar activity but also of the magnetic dipole moment of the Earth.4Though complex, this history of the earth’s magnetic field agrees with Barnes’ basic hypothesis, that the field has always freely decayed....
The illustration below shows the three isotopes of carbon.
Atoms are made up of much smaller particles called protons, neutrons, and electrons.
The atomic number corresponds to the number of protons in an atom.
