It is formed high up in the atmosphere by cosmic radiation coming from outer space. The newly formed carbon-14 has high energy at the moment of its formation, so that it rapidly oxidizes to carbon dioxide, which spreads out and distributes itself evenly in the atmosphere.
The ratio of carbon-14 in the carbon dioxide of the atmosphere is very low.
