Desintegración beta del tritio

3H → 3He + e + ν̄e

Descripción general

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.
