Carbon-14 goes through radioactive beta decay: 6C → 7N + e + ν e + 156.5 keV By emitting an electron and an electron antineutrino, one of the neutrons in carbon-14 decays to a proton and the carbon-14 (half-lifef 5,700 ± 30 years ) decays into the stable (non-radioactive) isotope nitrogen-14. As usual with beta … See more
