QWhat is tritium?
ATritium (hydrogen-3) is a form of hydrogen and exists naturally all around us.

Tritium (hydrogen-3) is a form of hydrogen. It occurs naturally due to cosmic rays (radiation from space) interacting with atmospheric gases, and reacts with oxygen to become tritiated water. Tritiated water exists in water vapor in the atmosphere, in the ocean, in tap water and food, and in the human body.
