Krypton-83 has application in magnetic resonance imaging (MRI) for imaging airways.In particular, it enables the radiologist to distinguish between hydrophobic and hydrophilic surfaces containing an airway.
Being radioactive, it has a half-life of 230,000 years.Krypton gas is also combined with other gases to make luminous signs that glow with a bright greenish-yellow light.A brighter light results with more blue color than conventional incandescent lamps.Abstracts in recent Red Books, and full papers in Red Books 1 to 320 ( except 24, 25, 26 and 50), are available to view/download as pdfs. Blue Books use the 'Category' option in the Search area.kryptos "the hidden one") is a chemical element with symbol Kr and atomic number 36. A colorless, odorless, tasteless noble gas, krypton occurs in trace amounts in the atmosphere and is often used with other rare gases in fluorescent lamps. Krypton, like the other noble gases, is used in lighting and photography.Neon was discovered by a similar procedure by the same workers just a few weeks later.
William Ramsay was awarded the 1904 Nobel Prize in Chemistry for discovery of a series of noble gases, including krypton.
At the same time, that mixture would contain only 10% oxygen (rather than the normal 20%) and hypoxia would be a greater concern.
He in Guarani groundwater discharge accounts for about 20% of the assumed global flux from continental crust, and that other large aquifers may account for about 33%.
Krypton's white discharge is often used to good effect in colored gas discharge tubes, which are simply painted or stained to create the desired color (for example, "neon" type multi-colored advertising signs are often entirely krypton-based).
Krypton produces much higher light power than neon in the red spectral line region, and for this reason, red lasers for high-power laser light-shows are often krypton lasers with mirrors that select the red spectral line for laser amplification and emission, rather than the more familiar helium-neon variety, which could not achieve the same multi-watt outputs.
Krypton's concentration in the atmosphere is about 1 ppm.
