Kr-78 Information

Krypton is a colorless gaseous element, belongs to the noble gases. It occurs in the air, 0.0001% by volume. This element can be extracted from liquid air by fractional distillation. Generally krypton is not isolated, but it is used with other inert gases in fluorescent lamps. It has 33 isotopes. 6 of them are natural, 5 of which are stable. Kr-85, the most stable radioactive isotope, has a half-life of 10.76 years and it is produced in fission reactors. Krypton is practically, though it is known to form compounds with Fluorine.

Krypton is used in lighting products. Some of its compounds are used as inert filler-gas in incandescent bulbs. Some of its compounds are mixed with argon in fluorescent lamps. The most important usage of krypton is in flashing stroboscopic lamps that outline airport runways.
