Krypton and Xenon – Applications
Krypton
Krypton’s multiple emission lines make ionized krypton gas discharges appear whitish, which in turn makes krypton-based bulbs useful in photography as a white light source. Krypton is used in some photographic flashes for high speed photography. Krypton is also used in MRI/CT techniques.
Xenon
Xenon is useful in the following applications. The white flash of light produced by xenon makes it suitable for usage in strobe lights and to power ruby lasers. Xenon is used in light-emitting devices called xenon flash lamps, used in photographic flashes and stroboscopic lamps.
