Tritium Tube of 1.5*6mm

Tritium lighting is made using glass tubes with a phosphor layer in them and tritium gas inside the tube. Such a tube is known as a "gaseous tritium light source" (GTLS), or beta light (since the tritium undergoes beta decay).The tritium in a gaseous tritium light source undergoes beta decay, releasing electrons that cause the phosphor layer to phosphoresce. Tritium presents no external beta radiation threat when encapsulated in non-hydrogen-permeable containers due to its low penetration depth, which is insufficient to penetrate intact human skin.  Dimensions1.5*6mm Features Requires no electrical energy Glows for as long as 25 years Safety The primary danger from tritium arises if it is inhaled, ingested, injected, or absorbed into the body. This results in the absorption of the emitted radiation in a relatively small region of the body, again due to the low penetration depth. The biological half-life of tritium – the time it takes for half of an ingested dose to be expelled from
