tritium illumination

Tritium illumination is a self-powered form of illumination that is used in the tactical, watch, and aerospace industries due to its reliability.
Tritium watches glow up to 100 times more brightly than ordinary luminescent watches and require no external light source to recharge the illumination.
The biggest advantage of Tritium illumination is that it provides a constant glow throughout the night unlike traditional illumination such as
Super-LumiNovawhich will gradually fade in a matter of hours.

WHAT IS TRITIUM?

Tritium is a radioactive isotope of hydrogen with the symbol T or 3H. It has one proton and two neutrons in its nucleus, making it heavier than the most common hydrogen isotope. Tritium has a half-life of about 12.3 years, meaning that it takes that amount of time for half of the tritium to decay into helium-3, which is a stable isotope of helium. The beta rays emitted from tritium can be shielded with a thin sheet due to their low energy.
Tritium occurs naturally in the upper atmosphere when cosmic rays strike nitrogen molecules in the air. It can also be produced during nuclear weapons explosions and as a byproduct in nuclear reactors. Tritiated water, which is water containing tritium, has a biological half-life of 10 days but can bind to proteins, fat, and carbohydrates in the body with an average 40-day half-life.
Although large quantities of tritium have been released into the environment, human exposure to tritium is small because it primarily enters the body when people swallow tritiated water, inhale tritium as a gas in the air or absorb it through their skin. Tritiated water moves through the environment like ordinary water and can enter nutrients such as carbohydrates, fats or proteins. Tritium consumed in food poses a slightly greater health risk than tritiated water because it retains longer in the body.

HOW DO THE TRITIUM ILLUMINATION WORK?

Tritium illumination works by using small amounts of tritium in combination with a phosphor material. Tritium is a radioactive isotope of hydrogen, with a nucleus containing two neutrons that are not usually present in hydrogen atoms. The tritium emits electrons through beta-decay, which excite the phosphor and cause it to emit visible light. Tritium radioluminescence is the use of gaseous tritium to create visible light. The electrons emitted by the tritium come into direct contact with the phosphor, resulting in the phosphor being energized and producing continuous light output.
Tritium glow lights are marketed as self-illuminating safety devices for identifying a location in hours of darkness or low visibility conditions. They can be used for exit signs, watch tiles, flashlights, and rifle sights. In exit signs, tritium gas is contained in sealed glass vials lined with a light-emitting phosphorous compound; the isotope emits low-energy radiation that causes the compound to glow continuously for up to 20 years without requiring any external power source.Aquatico Watches uses Swiss-made tritium illumination in each and every watch due to its unwavering reliability and readability in all conditions.
The tritium illumination used in Aquatico watches is completely safe.

TRITIUM FOR THE WATCHES

Tritium is a radioactive isotope of hydrogen that is used in self-illuminating watches. Tritium gas is sealed inside tiny glass tubes, which are coated with a thin layer of phosphor powder and then exposed to electrons. This creates a low-level light that glows continuously for up to 25 years. Tritium watches are popular among military personnel due to their ability to be read in low light or total darkness. They are also available commercially, with brands such as Aquatico offering tritium dive watches on Aquaticowatch.com.

HOW LONG DOES THE TRITIUM LAST ON THE WATCHES?

Tritium has a half-life of 12 years. This means that after 12 years, half of the glow will be gone, and after another 12 years, only 25% of the original glow will remain[1]. Tritium gas is used in tubes for lume applications in modern watches. The tritium constantly emits electrons through beta decay, which interact with a phosphorous material to create a fluorescent light that can last up to 20 years.
There are conflicting reports on how long tritium glows usefully for. Some posts claim that it glows usefully for 10, 15 or even 20 years, while others state that the useful glow is only a few years. However, tritium watches are known for holding a constant and bright glow for up to 25 years thanks to the use of tritium gas inside borosilicate glass capsules.
In summary, tritium has a half-life of 12 years and its glow will diminish over time. Tritium gas is used in tubes for lume applications in modern watches and can last up to 20 years. However, tritium watches are known for holding a constant and bright glow for up to 25 years.

ARE THERE ANY SAFETY CONCERNS WITH TRITIUM WATCHES?

Tritium watches are not dangerous and are safe to wear. Tritium emits a very weak beta particle, and people are exposed to small amounts of radiation. The only way tritium can be dangerous is if it is ingested. A person who wore a BP with tritium painted hands and indices continuously from 2000 to 2009 did not experience any health concerns related to the minimal radiation in tritium watches.
Tritium is a beta-emitter with low energy of up to 19 keV and a half-life of 12.3 years. Until the middle of the 90s, paints that were enriched with Tritium (H-3), a radioactive isotope of Hydrogen, were used for marking luminous dials. However, Tritium as a volatile substance could diffuse through the underside of the watch casing, which was made from plastic in these watches, and could be harmful to persons manufacturing them.
In conclusion, there are no safety concerns with wearing tritium watches. The minimal radiation emitted by tritium is not harmful unless ingested. However, persons manufacturing watches containing Tritium should take precautions due to its volatility.

WHAT ARE THE BENEFITS OF TRITIUM WATCHES?

Tritium watches have several benefits over traditional luminescent watches. Tritium illumination provides a constant glow throughout the night, unlike traditional illumination such as Super-LumiNova which gradually fades in a matter of hours. The legibility of tritium is superb and does not fade through the night. Tritium watches glow up to 100 times more brightly than ordinary luminescent watches and require no external light source to recharge the illumination.
One of the biggest advantages of tritium watches is that they do not need batteries or an external light source to charge them up. This means that they are always ready to use, even in low-light conditions. Tritium constantly emits large quantities of electrons, which collide with the luminescent layer on the inside of the glass tube, creating a constant glow.
Tritium watches are also popular among military personnel and elite forces because they provide good sight acquisition in low-light conditions. They are also durable and can withstand harsh environments. Several brands offer tritium watches, including Aquatico, Armourlite, IsoBright Watches, Traser Watches, H3 Tactical Watches, UZI Watches, Smith and Wesson Watches, Wrist Armor Tritium Watches and Mondaine Watches.

TRITIUM T25 VS T100, WHICH IS BETTER AND WHAT'S THE DIFFERENCE?

Tritium is a radioactive isotope of hydrogen that is used to illuminate watch dials. The T25 and T100 designations refer to the amount of tritium gas that is hermetically sealed in the glass tubes in a watch. T25 watches have up to 25 mCi (millicuries) of tritium gas, while T100 means there is up to 100 mCi of tritium gas in the watch. The radiation content of watches with a T25 mark contains no more than 25mCi of radiation content, and similarly, watches with a T100 mark contain no more than 100mCi.
T100 represents the latest technology in tritium watches and makes seeing the time in the dark much easier on the eyes. The increased visible brightness of T100 makes it four times brighter than traditional T25 strength Tritium used by virtually all their competitors. However, it should be noted that both T25 and T100 are safe for human use as they emit low levels of radiation.
In summary, the difference between Tritium T25 and Tritium T100 is the amount of tritium gas that is hermetically sealed in the glass tubes in a watch. Watches with a T25 rating contain up to 25mCi of radiation content, while watches with a T100 rating contain above 25mCi and up to 100mCi. The increased visible brightness of Tritium T100 makes it four times brighter than traditional Tritium strength used by virtually all their competitors.

HOW TO CARE YOUR TRITIUM WATCH?

 Tritium watches are different from other watches because they use a radioactive isotope of hydrogen called Tritium H-3 as the luminous substance on watch dials. The substance doesn't glow on its own but needs to be activated or "charged" by an external light source. It is important to mention that Tritium used for Rolex watches with luminescent parts is not harmful when sealed inside the watch.

To care for your tritium watch, it is recommended to remove the dial and hands of radium/tritium watches while wearing nitrile gloves and place them in a secure location. If you need to restore your tritium watch, it is best to clean it up and possibly fix anything that is broken without re-luming or re-finishing it.
It is essential to handle tritium watches with care. If you need to open your tritium watch, make sure you know what you are doing and take necessary precautions. It would be best if you did not repeat mistakes made in the past when opening watches without knowing that there were other radioactive materials used apart from radium.
