A breathing mixture of 30% xenon and 30% krypton is comparable in effectiveness for CT to a 40% xenon fraction, while avoiding the unwanted effects of a high partial pressure of xenon gas. [45] The metastable isotope krypton-81m is used in nuclear medicine for lung ventilation/perfusion scans , where it is inhaled and imaged with a gamma camera ...
Because of its scarcity, xenon is much more expensive than the lighter noble gases—approximate prices for the purchase of small quantities in Europe in 1999 were 10 €/L (=~€1.7/g) for xenon, 1 €/L (=~€0.27/g) for krypton, and 0.20 €/L (=~€0.22/g) for neon, [67] while the much more plentiful argon, which makes up over 1% by volume ...
The European energy-saving krypton T8 lamps were introduced by Thorn EMI during the 1970s. [4] The North American energy-saving argon T8 lamps weren't introduced until the 1980s. [5] T9 T29 1 + 1 ⁄ 8: 28.6 G10q quad-pin; G13 bi-pin; Circular fluorescent tubes; Some linear tubes; T10 1 + 1 ⁄ 4: 31.75 G13 bi-pin; G10q quad-pin
A flicker light bulb, flicker flame light bulb or flicker glow lamp is a gas-discharge lamp which produces light by ionizing a gas, usually neon mixed with helium and a small amount of nitrogen gas, by an electric current passing through two flame shaped electrode screens coated with partially decomposed barium azide. The ionized gas moves ...
Krypton, which is more advantageous than argon due to its higher atomic weight and lower thermal conductivity (which also allows use of smaller bulbs), but its use is hindered by much higher cost, confining it mostly to smaller-size bulbs. Krypton mixed with xenon, where xenon improves the gas properties further due to its higher atomic weight ...
Krypton-85, with a half-life 10.76 years, is formed by the fission process with a fission yield of about 0.3%. Only 20% of the fission products of mass 85 become 85 Kr itself; the rest passes through a short-lived nuclear isomer and then to stable 85 Rb. If irradiated reactor fuel is reprocessed, this radioactive krypton may be released into ...
