Element Uses

Krypton is not used commonly, because it is difficult and very expensive to obtain. However, krypton is used in fluorescent lamps, often with argon. It is also used in high-speed photographic flashes and lightning airfields because it has an extremely fast response to electric currents and can penetrate fog and haze easily. Krypton is also used with phosphorus to produce materials that glow in the dark. Krypton is occasionally used with other gases to produce a luminous, glowing light, like its "cousin", neon.
