Beta Decay of Carbon-14

¹⁴C → ¹⁴N + e⁻ + ν̄_e

Ikhtisar

Carbon-14 undergoes beta-minus decay to nitrogen-14, emitting an electron and an antineutrino. C-14 has a half-life of 5,730 years and is continuously produced in the atmosphere by cosmic ray neutrons interacting with nitrogen. The ratio of C-14 to C-12 in organic remains decreases after death, enabling radiocarbon dating.
