Tarix
Scottish chemist Sir William Ramsay and his assistant English chemist Morris Travers discovered krypton in 1898 in London.

They found krypton in the residue left from evaporating nearly all components of liquid air.

William Ramsay was awarded the 1904 Nobel Prize in Chemistry for discovery of a series of noble gases, including krypton.

Qo‘llanilish sohalari
Krypton is used in certain photographic flash lamps for high-speed photography.

Krypton-83 has application in magnetic resonance imaging (MRI) for imaging airways.

Krypton is used as a filling gas for energy-saving fluorescent lights and as an inert filling gas in incandescent bulbs.
Krypton is considered to be non-toxic
