Xenon-129 is currently being used as a visualization agent in MRI scans. When a patient inhales hyperpolarized xenon-129 ventilation and gas exchange in the lungs can be imaged and quantified. Unlike xenon-133, xenon-129 is non-ionizing and is safe to be inhaled with no adverse effects. [182]
[1] [2] 129 Xe is a stable, naturally occurring isotope of xenon with 26.44% isotope abundance. It is one of two Xe isotopes, along with 131 Xe, that has non-zero spin, which allows for magnetic resonance. 129 Xe is used for MRI because its large electron cloud permits hyperpolarization and a wide range of chemical shifts
A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure. It produces a bright white light to simulate sunlight , with applications in movie projectors in theaters , in searchlights , and for specialized uses in industry and research.
Xenon-129 is a safe inert noble gas that can be used to quantify lung function. With a single 10-second breath hold, hyperpolarized Xenon-129 is used with MRI to enable 3-dimensional lung imaging. [35] Xenon MRI is being used to monitor patients with pulmonary-vascular, obstructive, or fibrotic lung disease. [36]
To separate the 129 Xe from the helium and nitrogen, it is cryogenically accumulated in a cold finger immersed in liquid nitrogen. Since xenon has a higher freezing point than the other gases, it is frozen out and separated from them. Once a sufficient amount of xenon has been accumulated, it is thawed and dispensed into a perfluoropolymer bag.
Xenon lamp may refer to: Xenon arc lamp; Xenon flash lamp; An incandescent light bulb filled with xenon gas to improve life span or efficiency;

Super Trouper is a registered trademark for a series of follow spotlights used in stadium, concert, and special-event lighting. The lights are manufactured by Strong Lighting of Omaha, Nebraska, which acquired the Super Trouper and its larger cousin, the Gladiator, from its former manufacturer Syncrolite who had acquired them from Ballantyne Strong of Omaha, Nebraska (originally Strong ...
