  • Carbon, though, is continuously created through collisions of neutrons generated by cosmic rays with nitrogen in the upper atmosphere and thus remains at a near-constant level on Earth.
  • When an organism dies, it ceases to take in new carbon, and the existing isotope decays with a characteristic half-life years.
  • Radioactive isotopes are used to test wear and tear inside a car engine.
