Nonetheless, tritium is dear—it must be built in the nuclear reactor—and it's got a half-life of only about twelve many years so the paint stays luminous for just a few years. Currently, tritium is Utilized in specialised watches, e.g., for armed forces purposes (See Tritium illumination). For other reasons, luminous paint is typically utilized on analog shows, but no radioactive substance is contained in it. Which means the Display screen glows soon immediately after being exposed to light and swiftly fades.
