How dangerous is tritium?
Since tritium is a low energy beta emitter, it is not dangerous externally (its beta particles are unable to penetrate the skin), but it can be a radiation hazard when inhaled, ingested via food or water, or absorbed through the skin.
Does tritium glow forever?
The electrons emitted by the radioactive decay of the tritium cause phosphor to glow, thus providing a long-lasting (several years) and non-battery-powered firearms sight that is visible in dim lighting conditions.

How long does Lume last on a watch?
Radium dials still glow and will for another 50,000 years. Tritium Beta activity halves itself every 12.5 years and so after about 20 years it won’t be powerful enough to excite the paint matrix. Lumonova (or Rolex name Chromalite) is photo-sensitive (photo-luminescence) paint and so it can be recharged.
