Does tritium lose glow?

Since Tritium is radioactive, it will glow whether or not it receives any light exposure; however its ability to glow is limited by the radioactive half-life of the material itself. This means that as Tritium ages, its ability to glow will diminish until the point that it ceases to glow at all.

Does tritium fade overtime?

Tritium fades over time and changes color, giving it a cool patina.

Does tritium need to be charged?

Tritium is a radioactive isotope of Hydrogen. Tritium light sources are radioluminescent and can be best described as a strong glow. They are self-powered and do not need to be charged via exposure to light, such as our Glow in the Dark Embrite™ glow material.

Do tritium sights need sunlight?

Optical fiber and gold or brass bead front sights help by concentrating light from external sources, but now we have something better — tritium night sights. These sights glow in the dark without the need for an external light or power source and do not need to be charged with an external light.

How long will tritium glow for?

Since Tritium half-life is 12.3 years and concentration of tritium is close to 2 half-lifes, expect up to 24 years of noticeable glow action… From the moment the vial is filled, the tritium begins to deteriorate giving off beta radiation (electrons) with a half life of 12.3 years.

Which tritium color is brightest?

Green
The difference between the signs is how much tritium the manufacturer installs. The light produced by GTLSs varies in color and size. Green usually appears as the brightest color and red the least bright.

How long do tritium tubes glow?

However, tritium gas tubes have a half life of 12 years and will need to be replaced after roughly 24 years (modern lume such as Super LumiNova doesn’t last forever, either). Tritium glows less brightly than many lume applications at full charge, but will often be brighter within the first hour as the lume fades.

Is tritium still used in watches?

Although tritium paint is still used today for watch lume, it was most commonly used in the 1960’s through about the late 1990’s or early 2000’s. Also used during this time, however much more rarely, was promethium, another radioactive material used for self-luminous watch applications.
