Tritium night sights have become increasingly popular for conceal-carry pistols and quick acquisition alignment when shooters do not want to add red dots or other sights to their handguns. The topic of this post is whether these tritium night sights are safe or harmful to the person using them. In our current world, chemicals are a constant barrier to providing something of value to the human population or harming both the environment and the health of individuals.

Key Takeaways

• Tritium is a radioactive substance widely used in night sights.
• Sights equipped with tritium rear sights are indispensable to various weapons of military personnel, police officers and civilians.
• Tritium glows in the dark, making the sight visible at night without additional light sources.
• Night sights with tritium inserts are safe if used correctly.

What Is Tritium?

Tritium is a radioactive isotope of hydrogen. This substance has a long half-life (12 years) but gradually turns into helium. Radioactive tritium is found in the atmosphere around us and, in small concentrations, is safe for humans. That is why it is actively used to create wristwatches, sights, and other devices often used in low-light conditions.

The Science Behind the Technology

Tritium gas was discovered in the atmosphere in the mid-1930s. It immediately attracted the attention of scientists, but at that time, it was impossible to find a suitable application for it. However, this substance has become indispensable in creating various night devices many years later.

Tritium can emit beta particles. They accumulate and form a flow called beta radiation. It affects the phosphorus material, which creates visible light. If we consider the whole process in more detail, special tritium vials are used to obtain the necessary glow. They are made of glass and pre-coated with an available phosphorus-based material. Under the influence of tritium, the latter begins to emit light visible in the dark. Depending on the phosphorus composition, the glow can have a different shade. The most popular option is green. The life of tritium is 12 years, so the substance can remain helpful to humans during this time. Its use in modern night sights gives its owners a huge advantage and allows them to aim without any illumination.

Tritium for Sights & Scopes

Tritium has recently been used in night sights and other optics. This substance can create a bright glow without consuming battery power, essential when sights are used continuously for a long time. Tritium is used on the rear and front sights. It also helps illuminate the aiming grid. Thanks to this, the shooter can see the dot sight and the entire sight picture even in complete darkness.

What Are the Benefits of Tritium Sights?

Tritium sights are popular optics in demand in various fields of activity. This has become possible due to several significant advantages compared to models of other types. According to experts and ordinary users, the main benefit is the operation efficiency in low light. Tritium can create a visible glow, which allows the shooter to see the aiming grid. This positively affects the accuracy of shooting not only in low light conditions but also in complete darkness.

The following significant advantage is the versatility of tritium sights. They are suitable for use on different types of weapons, making them indispensable for hunters, police officers, military personnel, security guards and representatives of other professions. The ability of tritium to create visible light without using battery power is no less significant. Thanks to this, the battery life of the night sight can be increased, relieving the need for the user to use external power sources.

People who regularly use tritium sights note the ease of their operation. For effective aiming, you do not need special knowledge and skills, making this optics an ideal option for beginners. Simplicity is also seen in the maintenance of the sight. This process does not take much time and does not require significant financial costs. Tritium has made Night Sights more reliable and durable than its competitors. This advantage makes it possible to use the purchased model for a long time without fear of breaking at the most critical moment.

Finally, the last significant advantage of tritium sights is their financial accessibility. Many models can be purchased at an adequate price, which, considering the almost complete absence of costs for maintenance and care, makes this optics a priority option for people with different financial capabilities. Tritium sights also have many more minor advantages that only improve the overall impression of them.

Are Tritium Night Sights Safe?

Tritium itself can be dangerous if consumed by inhalation or ingestion, as large amounts can cause radiation poisoning. Because the tritium night sights are in contained sights, there is no risk of radiation exposure. Tritium molecules can travel just 6mm in the air before losing their radioactive charge. One area to be highly cautious of is if a tritium sight is cracked or damaged; it could prevent exposure and potential health risks. This should add further reason to carrying tritium sight-bearing arms in a proper holster or case. There are no added health or risk concerns with using tritium night sights as long as the protective barrier protecting these sights remains intact. The same can be said about the old glass thermometers containing mercury.

Tritium is widely known as a by-product of nuclear fusion in energy- and weapons-oriented operations. Currently, tritium is unavoidably emitted into the air and water. This is usually in trace amounts, later mixed with large amounts of water or air and deemed harmless. Tritium is also present in the natural world due to gamma rays that reach the earth.

Tritium night sights aren’t the only use of tritium in the industrial/commercial market. Tritium is also used in self-illuminating exit signs, clock faces and varying glow-in-the-dark keychains. Tritium itself does not inherently glow. Phosphorus is added to these applications/devices, where the tritium stimulates the phosphorus molecules until they are glowing; this is how they can glow both during the day and at night. Tritium is a relatively short-lived surface as its half-life is 12.5 years, meaning it will burn out and no longer be active.

Conclusion

As mentioned with any chemicals or compounds, you must take extreme caution when storing and operating the tritium night sights. You should also inspect to ensure there is no physical damage to the sites' housing. The manufacturers of these devices know of these risks and have provided highly durable and rugged designed housings for these sites to prevent any potential exposure. Tritium is a valuable tool in training, targeting, conceal carry, and home defense. The ability for your sights to glow in both the day and dark provides an immediate advantage for quick acquisition or nighttime application. You can imagine how difficult it would be to co-align your standard sights on a handgun during the dark in your house, hoping that situation would never arise. Tritium night sights are beneficial in their aid and application but carry some added health concerns due to the radiation exposure that makes up this molecule.

FAQ

How Long Do Tritium Night Sights Last?

Tritium has a half-life of 12 years, so night vision sights that use this substance for illumination can remain effective for the same amount of time.

Is Tritium Better Than Fiber Optic Sights?

In most cases, tritium is better than fiber optic sights. It remains effective for the longest time, allows you to aim even in complete darkness, and does not use any power sources to create a glow.
