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. 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. This is truly a ''nuclear powered'' gadget!

These pendants can be worn 24/7 but since the vials are made of glass, care is advised to avoid shocks that may damage them. Do not expose in situations such as diving, dropping them in hard surfaces, extreme temperatures etc.
