Krypton Krypton - Kr General Information Discovery Krypton was discovered by Sir William Ramsey and M.W. Travers in 1898 in London, in the residue remaining after liquid air had boiled away. Appearance Krypton is a colourless, odourless gas. Source Krypton is obtained by distillation from liquid air. Uses Krypton is used commercially as a low-pressure filling gas for fluorescent lights. It is also used in certain photographic flash lamps for high-speed photography.
Radioactive krypton is used to estimate Soviet nuclear production.
The gas is a product of all nuclear reactors, so the Russian share is found by subtracting the amount that comes from Western reactors from the total in the air. Biological Role Krypton has no known biological role.
