Tritium presents no external radiation threat when encapsulated in non-hydrogen-permeable containers due to its low penetration depth, which is insufficient to penetrate intact human skin. The primary danger from tritium arises if it is inhaled, ingested, injected or otherwise absorbed into the body.
Natuurlijk straling is in België een veel groter probleem (in België +700 doden/jaar):Direct, short-term exposure to small amounts of tritium is relatively harmless. If a tritium tube should break, one should leave the area and allow the gas to diffuse into the air. Tritium exists naturally in the environment, but in very small quantities.
