Radiological Training for Tritium Facilities
Show OT 11
Tritium atoms can easily substitute for
hydrogen atoms. Examples:
elemental hydrogen (tritium gas,
HT, DT, or T2)
Show OT 12
tritiated water (tritium oxide: HTO,
DTO, or T2O)

tritium in air is between 4% and
75% by volume in air.
Tritium gas is flammable and can explode
under certain conditions.
