FactSnippet No. 624,784

Xenon emits a band of emission lines that span the visual spectrum, but the most intense lines occur in the region of blue light, producing the coloration.

FactSnippet No. 624,785

Xenon is obtained commercially as a by-product of the separation of air into oxygen and nitrogen.

FactSnippet No. 624,786

FactSnippet No. 624,787

Xenon-135 is a notable neutron poison with a high fission product yield.

FactSnippet No. 624,788

Xenon-136 is produced when xenon-135 undergoes neutron capture before it can decay.

FactSnippet No. 624,789

Xenon is a tracer for two parent isotopes, xenon isotope ratios in meteorites are a powerful tool for studying the formation of the Solar System.

FactSnippet No. 624,790

Xenon inferred that this was a decay product of radioactive iodine-129.

FactSnippet No. 624,791

Xenon tetrachloride is more unstable that it cannot be synthesized by chemical reactions.

FactSnippet No. 624,792

Xenon can be directly bonded to a less electronegative element than fluorine or oxygen, particularly carbon.

FactSnippet No. 624,793

Xenon is used in light-emitting devices called xenon flash lamps, used in photographic flashes and stroboscopic lamps; to excite the active medium in lasers which then generate coherent light; and, occasionally, in bactericidal lamps.

FactSnippet No. 624,794

Xenon is used as a starter gas in metal halide lamps for automotive HID headlights, and high-end "tactical" flashlights.

FactSnippet No. 624,795

Xenon is used as a "starter gas" in high pressure sodium lamps.

FactSnippet No. 624,796

Xenon has been used as a general anesthetic, but it is more expensive than conventional anesthetics.

FactSnippet No. 624,797

Xenon is an effective inhibitor of plasma membrane Ca ATPase.

FactSnippet No. 624,798

Xenon is a competitive inhibitor of the serotonin 5-HT3 receptor.

FactSnippet No. 624,799

Xenon induces robust cardioprotection and neuroprotection through a variety of mechanisms.

FactSnippet No. 624,800

Xenon is a high affinity antagonist at the NMDA receptor glycine site.

FactSnippet No. 624,801

Xenon is cardioprotective in ischemia-reperfusion conditions by inducing pharmacologic non-ischemic preconditioning.

FactSnippet No. 624,802

Xenon allosterically reduces ATP mediated channel activation inhibition independently of the sulfonylurea receptor1 subunit, increasing KATP open-channel time and frequency.

Xenon, particularly hyperpolarized Xe, is a useful contrast agent for magnetic resonance imaging.

FactSnippet No. 624,804

Xenon-129 is currently being used as a visualization agent in MRI scans.

FactSnippet No. 624,805

Xenon is the preferred propellant for ion propulsion of spacecraft because it has low ionization potential per atomic weight and can be stored as a liquid at near room temperature, yet easily evaporated to feed the engine.

FactSnippet No. 624,806

Xenon is inert, environmentally friendly, and less corrosive to an ion engine than other fuels such as mercury or caesium.

FactSnippet No. 624,807

Xenon was first used for satellite ion engines during the 1970s.

FactSnippet No. 624,808

Xenon difluoride is used as an etchant for silicon, particularly in the production of microelectromechanical systems.

FactSnippet No. 624,809

Xenon is non-toxic, although it does dissolve in blood and belongs to a select group of substances that penetrate the blood–brain barrier, causing mild to full surgical anesthesia when inhaled in high concentrations with oxygen.

FactSnippet No. 624,810

Xenon is rarely used in large enough quantities for this to be a concern, though the potential for danger exists any time a tank or container of xenon is kept in an unventilated space.
