The principle of tritium gas tube luminescence
The luminous principle of the tritium gas tube is based on the radioactive properties of tritium. Tritium is an isotope of hydrogen that releases high-speed electrons through beta decay. These electrons collide with gas molecules in the glass tube during flight, causing the gas molecules to become ionized. When these ionized gas molecules are activated by fluorescent substances in the tritium gas tube, they release photons, thereby producing visible light
Dimensions: 33mm long (not including titanium ring), 9mm in diameter, and weighs about 4 grams.

More COOL uses: remove the metal hanging ring and string it on a necklace. This is a COOL necklace pendant. In KTV, bars, discos, any dark place, only your body is shining! !
