About Tritium

Tritium illumination works via the use of gaseous tritium, a very slightly radioactive isotope of hydrogen, to create visible light.

Tritium emits electrons through beta decay. When these electrons interact with a phosphor material, fluorescent light is created, a process called radioluminescence. The light produced looks very much like a fluorescent light, although the color spectrum is more akin to that of neon.

Tritium illumination requires no electricity, it found wide use in applications such as emergency exit signs and illumination of wristwatches. Unlike photoluminescent materials, tritium does not need to be ‘charged’ by exposure to sunlight or incandescent lights.

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). These tubes are encased in high impact resistant lucite and other materials to make them perfectly safe to handle or for every day use.

The tritium in a gaseous tritium light source undergoes beta decay, releasing electrons which cause the phosphor layer to fluoresce.

How Tritium Light Sources Are Made

  • A length of borosilicate glass tube which has had the inside surface coated with a phosphor-containing material is filled with tritium.
  • The tube is then thermally fused with a CO2 laser at the desired length. Borosilicate is most often used because of its strength and resistance to breakage.
  • We then take this completed tube and encapsulate it in high impact lucite.

In the tube, the tritium gives off a steady stream of electrons due to beta decay. These particles excite the phosphor, causing it to emit a low, steady glow.

Are there other materials that glow besides Tritium?
Tritium is not the only material that can be used for self-powered lighting.
Other beta particle-emitting radioisotopes may also be used to create ‘perpetually’ glowing surfaces and products.
Radium was used in the past to make self-luminous paint, but has been replaced by tritium, which is less hazardous. The key dangers with radium were from ingesting it. Many years ago when workers would hand paint the radium onto watch dials, they would often ‘sharpen’ the tip of the paintbrush with their lips – not a safe practice.

Various preparations of the phosphor compound can be used to produce different colors of light. Some of the colors that have been manufactured in addition to the common phosphorus are green, red, blue, yellow, purple, orange, and white.
