Tritium lighting is made using glass tubes with a phosphor layer in them and tritium (a hydrogen isotope) gas inside the tube. Such a tube is known as a "gaseous tritium light source" (GTLS). Because tritium in particular is an integral part of thermonuclear devices (though in quantities several thousand times larger than that in a keychain), devices containing tritium are considered dual-use technology in the U.S.A., and are therefore illegal for export. However, they are widely available in the U.K., most of Europe (some countries like Belgium have outlawed them however), Asia and Australia. Tritium devices can be purchased in the UK and Australia, but are illegal for import to the United States, however they are available in the US as gunsights and for military applications. UK Source

What is the name of the isotope tritium?
Tritium. What did you think it was?
Why is tritium illegal in the us?
Tritium is not illegal in the US, but as with other radioisotopes it is regulated. It has many legal uses:radiochemical tracertiny amounts are used in neon lamps and signs to help them start faster and more reliablysealed ampules are used to make a phosphor glow to light watch and instrument dials ("safer" replacement for radium)electric activated neutron sources (used in petroleum and other industries)etc.
What color is tritium?
Tritium is an isotope of hydrogen, so it is colorless.
Identify two sources of white light?
The two sources of white light are: *visible light *The Sun.
Difference between of natural and artificial sources of light?
The difference between natural and artificial sources of light is that natural sources are produced by the sun while artificial light sources illuminate using energy from other sources and include incandescent bulbs.
What does acquired from external sources mean?
I means it has been taken or acquired from something else. E.g. the money was acquired from external sources, could be a bank.
What are light sources and non light sources?
The sources that can give out their own light are "Light Sources" and the same opposite the sources which can not give out their own light are know as Non Light Sources .
Name the nuclide that are sources of background radiation?
Isotopes of uranium, thorium, radium, radon, potassium, tritium, etc.
Which of these sources of energy have not acquired energy from sun?
Wind
What is the name of the isotope tritium?
Tritium. What did you think it was?
How does the sun emit radiant energy?
As an outcome of nuclear fusion of sun light elements ofDeuteriumand tritium

What is the oxide of tritium?
The oxide of tritium is tritium oxide, sometimes called super heavy water, or 3H2O.
How do you produce light?
We are not sources of light so we do not give off light.Light is given off by sources such as the Sun and Stars.Things that are not light sources reflect light into our eyes so we can see them.
Identify two sources of white light?
The two sources of white light are: *visible light *The Sun.
What color is tritium?
Tritium is an isotope of hydrogen, so it is colorless.
Are all heat sources are light sources?
no
