The radioluminescent light emitted by a trigalight® can be produced in several colours in the visible spectrum (green, yellow, orange, red, blue, ice-blue, white, purple and pink) as well as in infra-red. Light output is linear and follows a straight line to a half-life of 7 years. They require no external electrical supply (from mains or battery) nor do they need to be charged by ambient light. Trigalight® performance is predictable through their service life whether or not installed in permanent darkness and irrespective of weather conditions.
How safe is a Trigalight?
Because a trigalight® is non-emissive and utilises very low levels of energy, they are safe to use in a wide range of applications. For example, GTLS technology is type-approved for use in fire safety signs for the workplace under HSE Certificate of Approval No TA2.
Gaseous tritium produces electrons that are of sufficiently low energy as to be unable to breach a sheet of paper or to penetrate human skin. Nevertheless, care must be taken when handling these devices to avoid breakage and subsequent ingestion of residual gaseous tritium. Detailed information addressing aspects of human safety relating to GTLS is available upon request.
Tritium is Expensive! Cost: $30,000 per gram. Gaseous Tritium is also used in self-luminous fire safety signs which offer users the most advantageous life-cycle cost of any permanantly illuminated fire safety sign. Typically having a service life of 10+ years, self-luminous signs need no technical maintenance or spare parts during that time....
What is Tritium? First discovered by Mark Oliphant, Ernest Rutherford and Paul Harteck in 1934. It is a radioactive isotope of hydrogen mainly used in research activities, neutron generators and fusion reactors. Tritium is an isotope of Hydrogen with 2 Neutrons & 1 Proton, Deuterium has 1 neutron & 1 Proton and Hydrogen has 0 Neutron & 1 Proton. Our devic...
Radioluminescence Luminescence is the emission of light by materials that are relatively cool. This is different from the light emitted from incandescent materials, such as burning charcoal, wood, paper etc., as the light in those cases results from heat. Since the emission of light is done by relatively cooler materials, luminescence is also called cold-body radiation. Gaseous Tritium's...
