Nitrogen atoms high in the atmosphere can be converted to radiocarbon if they are struck by neutrons produced by cosmic ray bombardment.

The rate of bombardment is greatest near the poles, where the Earth's magnetic field is dipping into the Earth and therefore does not deflect incoming cosmic rays.

C is created in the atmosphere by cosmic radiation and is taken up by plants and animals as long as they live.

Upon death, the isotope begins to decay and after 5730±40 years half of it is gone.

Each radiocarbon date has a statistical probability shown by the ± number.
