Krypton is expensive to produce, which limits its use as an inert gas. It is used in a mixture with argon to fill incandescent light bulbs, fluorescent lamps, lasers, and high-speed photography lamps. Radioactive Kr-85 is used as a source of radiation to measure the thickness of industrial materials. It is also used to test for leakage of scientific instruments. 

Use Incandescent bulbs and fluorescent light tubes, lasers, high-speed photography. Note Solid krypton exists at cryogenic temperatures as a white, crystalline substance mp 116K. 

Prior to the advent of powerful lasers, high-speed flash techniques were employed as light sources in time-resolved studies. Research was focused mainly on luminescence studies, aimed at determining fluorescence and phosphorescence Hfetimes. In this connection, the development and successful apphcation of sophisticated methods such as the single-photon time-correlation method and high-speed photography methods (streak camera) are worthy of note. Detailed technical information on these topics is available in a book by Rabek [69].
