WebMar 16, 2024 · Step 1. High-energy cosmic rays, in the form of neutrons, strike nitrogen atoms in the upper atmosphere and convert them to the radioactive isotope of carbon, which is carbon-14 (also known as radiocarbon). This quickly oxidises to create mildly radioactive carbon dioxide. About 1.1 per cent of the carbon atoms on Earth are carbon-14.
