People may also inhale tritium as a gas or absorb it through their skin, but exposure to harmful levels of tritium through these exposure pathways is very unlikely.

  • from asteroids in space.
  • crystalised form as a Tritium Hypercluster.
  • some Galactic Trade Terminals.
  • in a Freighter after purchasing one.

Can tritium penetrate skin?

It is also a byproduct of the production of electricity by nuclear power plants. Tritium emits a weak form of radiation, a low-energy beta particle similar to an electron. The tritium radiation does not travel very far in air and cannot penetrate the skin.

Can you legally buy tritium?

In the US there are no legal sources of non sealed tritium vials. All Tritium vials must be sold new directly from a liscenced distributor. All re-sale of Tritium containing products are PROHIBITED in the US. § 30.19 Self-luminous products containing tritium, krypton-85, or promethium-147.

What color tritium is brightest?

Tritium does not in itself emit light but excites phosphors, thereby generating light. It is therefore most often encountered in glass capsules with an internal phosphor coating of various colors. Green is usually the brightest based on the phosphors and the sensitivity of the human eye.
