Through
its own research, the Swiss company mb microtec has
succeeded in manufacturing a self-activated light
source for use in wristwatches that is 100 times brighter
than any previously available. The light-emitting
devices, also known as Trasers, require no battery
power or any other form of external power supply,
do not require the push of a button, never need servicing
or maintenance, and have a useful life of more than
20 years.
A
Traser watch contains max. 1 GigaBecquerel (GBq)
Tritium,
a manmade radioactive isotope that also exists in
the natural environment. The Tritium decays to
helium
and in the process emits a low energy electron. The
gaseous Tritium in Traser watches is contained
in
a small hollow body of mineral glass, sealed air
tight with a laser.
The
surface of the watch is free of any radiation
because
the electrons do not penetrate the glass wall of
the vial nor the case of the watch. The GTLS (gaseous
tritium light source) in Traser watches are attached
in such a way that breakage and/or release of
the
gas is highly unlikely.
International
standards must be met, and Traser watches are
tested
to be in compliance with all mechanical and environmental
regulatory requirements relating to products of
this
nature. More specifically, Traser watches are licensed
by the Bundsamt fur Gesundheit (BAG-1971/7) in
Switzerland
(source country) and are approved for distribution
by the NRC (nuclear
regulatory commission) in the USA.
