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 Tritium vials used are light sources of gaseous tritium isotope, hermetically sealed in glass.
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.
