Tritium (symbol T or 3H, also known as hydrogen-3) is a radioactive isotope of hydrogen and one of the most valuable substances on earth, with a market price of 30.000$ per gram.
The vials used are light sources of the tritium isotope in gaseous form, hermetically sealed in borosilicate glass.

Tritium is considered “user friendly” because it has the lowest energy rating of any radioisotope. The energy of tritium electrons is much less than those generated in electrical lamps, which is why you cannot see tritium tubes glow, except in dim light or darkness.


This radioactive tritium gas glows completely on its own, in a very safe manner, without needing to be 'charged' with light as required by most phosphorescent glow in the dark products. The glow will be subtle and visible in low-light conditions; the darker the better. It will not be visible in daylight or well-lit areas. The light produced is literally ''ON'' at all times, it's intensity isn't reduced after a few hours and will last non-stop for about 20 years.

About Tritium isotope safety issues:


The question of how safe Tritium really is, often arises and should be addressed.

My own extensive research, indicates that there is no health concern when worn. I am not just a maker, I am also a user of my products.


A couple of links:


Tritium presents no external radiation threat via beta radiation when encapsulated in non-hydrogen-permeable containers due to its low penetration depth, which is insufficient to penetrate intact human skin. The primary danger from tritium arises if it is inhaled, ingested, injected, or absorbed into the body. This results in the absorption of the emitted radiation in a relatively small region of the body, again due to the low penetration depth.



The radioactive decay product of tritium is a low energy beta that cannot penetrate the outer dead layer of human skin. Therefore, the main hazard associated with tritium is internal exposure from inhalation or ingestion. In addition, due to the relatively long half life and short biological half life, an intake of tritium must be in large amounts to pose a significant health risk.


I should also state that I have a Geiger counter in my possesion which shows no activity from the vials (due to the fact of the very low emission that cannot escape the vial).
