Tritium Beta Decay

3H → 3He + e− + ν̄e

개요

Tritium (hydrogen-3) undergoes beta decay to helium-3 with a half-life of 12.3 years, emitting a very low energy electron (max 18.6 keV). The low beta energy means tritium radiation cannot penetrate skin and is only hazardous if ingested or inhaled. Tritium is produced in nuclear reactors and by cosmic rays.
