carbon 14

5. driver dell inspiron 14 5000 series 15 4 2 7 Carbon-14 Carbon-14 is produced in the atmosphere by a low-energy cosmic-ray neutron reaction with nitrogen It decays back to 14 N with a half-life of 5,730 yr The production rate is ∼2×10 4 atom m −2 s −1, the highest of all cosmogenic radionuclides The rate is so high, because nitrogen is the most abundant element in the
