Tritium Technology in Military Timepieces

mtm-camouflage-air-stryk-1-military-watch-2Tritium paint has already been utilized on the hands as well as numerals of watches because the 1930’s. At very first this technology was Best Secret and restricted in order to use on military timepieces.

Tritium paint on timepieces is really a mixture of tritium and phospor. Tritium is actually naturally radio-active and desires absolutely no external source of lighting or charge to function. Tritium does not shine. As it decays, tritium emits beta radiation, that are a group associated with excited electrons that within turn excite the electron in the phosphor atoms making them emit photons, or light. As these people return to their floor (non-excited) state, the phosphor glows. Phosphor may also be thrilled by UV light through the sun or some other light sources. Thus, the actual tritium paint relies upon tritium radioactivity to create the phosphor glow within the dark, not any kind of charge from external lighting source.

Tritium, features a 1 / 2 life of 12. three years, a half-life is merely the time it requires HALF of the tritium to decay. So because long as there is actually enough tritium in the actual paint, the watch will certainly glow for years.

Because of to the toxicity associated with tritium based paint, the new technology was created by mb-microtec in Swiss. This uses tritium fuel sealed in vials. The actual principle may be the same however the tritium gas leads to the coating within the vial to glow. The amount associated with radiation are so little that they pose absolutely no risk to the individual. This technology has already been used in the Traser H3, Luminox and Race military watches. In current years SRB of North america have developed an identical program, this is used through manufacturers such as Cruz and Wesson, Rescuer as well as NITE. SRB tritium is actually not as yet too developed as the mb-microtec technology, only offering about 80 – 90% associated with the luminescence.

The primary advantage of tritium within military watches is which there is no extra drain on the view battery to power the actual night source of light, however these types of watches get a disadvantage in that they may be selected up at great range by night vision gear. Therefore, it is important that these types of watches are covered throughout military operations at evening.

As the technology is becoming cheaper it is discovering its way into the actual civilian market. Many athletes such as anglers as well as shooters wear tritium dependent watches with Luminox as well as Traser being the most famous.

Every year more and much more manufacturers are bringing brand new tritium watches onto the actual market. As the tritium light sources from SRB become more popular as well as coupled with cheaper production within China, it won’t become long before we come across tritium used in purely civilian watches.
