The high cost of obtaining krypton from the air has limited its practical applications. Krypton is used in some types of photographic flashes used in high speed photography. Some fluorescent light bulbs are filled with a mixture of krypton and argon gases. Krypton gas is also combined with other gases to make luminous signs that glow with a greenish-yellow light.

In , the length of the meter was defined in terms of the orange-red spectral line of krypton, an isotope of krypton. Once thought to be completely inert, krypton is known to form a few compounds.

Krypton difluoride KrF 2 is the easiest krypton compound to make and gram amounts of it have been produced. Ramsay received the Nobel Prize in Chemistry. Krypton has a variety of uses today: in flashes for high-speed photography, in fluorescent lights in combination with argon, and to make so-called neon signs that have a greenish-yellow light. Neon itself glows red. Between and , the meter was defined as 1,, Retellings of Superman's origins place his arrival on Earth around the time of World War I, a mere 20 years after Ramsay and Traver's discovery of krypton.

Siegel and Shuster may have been inspired by the element's cryptic name, its ghastly glow or perhaps just its sound, like George Eastman favoring the strength of the letter K.
