Gaseous Tritium Side Dot Markers
Gaseous Tritium luminous side dot marker
These are the deluxe option (sold singly)
these 2mm by 12mm side dot markers are
made of a sealed glass vial containing a quantity of radioactive
Hydrogen Isotope (Tritium)
This is a beta emitter and is hence completely safe
the decay gives off light as the hydrogen H3 decays into helium
the light given off is constant and requires no charging
will work straight out of the case and glow all night and day.
decays slowly over time, expect these to stay bright
for at least ten years and then fade slowly
giving out usable light for over 30 years.
contained in a sealed vial of borosilicate glass
just drill a hole and glue the vial in place,
this is a gas, don't open the vial, glue it in as it comes.
