Xenon Xenon is a rare, odorless, colourless, tasteless, chemically unreactive gas. It was regarded as completely inert until, in 1962, Neil Bartlett reported synthesis of xenon haxafluoroplatinate. In a gas filled tube xenon emits blue light when excited by electrical discharge. Applications Xenon has relatively little commercial use. It is used in photographic flash lamps, stroboscopic lamps, high-intensitive arc-lamps for motion picture projection and high-pressure arc lamps to product ultraviolet light (solar simulators). Other uses are as general anaesthetic, xenon 'blue' headlights and fog lights are used on some vehicles and are said to be less tiring on the eyes. They illuminate road signs and markings better than conventional lights. Xenon in the environment Xenon is a trace gas in the Earth's atmosphere, occurring in 1 part in 20 million. The only commercial source of xenon is from industrial liquid-air plants. World production is less than 1 tonne per year, although reserved of xenon gas in the atmosphere amount to 2 billion tonnes. Health effects of xenon Inhalation: This gas is inert and is classified as a simple asphyxiant. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death. Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue. At low oxygen concentrations, unconsciousness and death may occur in seconds without warning. The effect of simple asphyxiant gases is proportional to the extent to which they diminish the amount (partial pressure) of oxygen in the air that is breathed. The oxygen may be diminished to 75% of it's normal percentage in air before appreciable symptoms develop. This in turn requires the presence of a simple asphyxiant in a concentration of 33% in the mixture of air and gas. When the simple asphyxiant reaches a concentration of 50%, marked symptoms can be produced. A concentration of 75% is fatal in a matter of minutes. Symptoms: The first symptoms produced by a simple asphyxiant are rapid respirations and air hunger. Mental alertness is diminished and muscular coordination is impaired. Later judgment becomes faulty and all sensations are depressed. Emotional instability often results and fatigue occurs rapidly. As the asphyxia progresses, there may be nausea and vomiting, prostration and loss of consciousness, and finally convulsions, deep coma and death. This agent is not considered a carcinogen. Effects of xenon on the environment Xenon is a rare atmospheric gas and as such is non-toxic and chemically inert. The extreme cold temperature (-244oC) will freeze organisms on contact, but no long term ecological effects are anticipated. Disposal considerations: When disposal becomes necessary, vent gas slowly to a well-ventilated out door location remote from personnel work areas and building air intakes. Do not dispose of any residual gas in compressed gas cylinders. Return cylinders to the supplier with residual pressure, the cylinder valve tightly closed. Please be advised that state and local requirements for waste disposal may be more restrictive or otherwise different from federal regulations. Consult state and local regulations regarding the proper disposal of this material. APPLICATIONS Xenon is used in incandescent lighting. Since less energy can be used to produce the same unit of light output as a normal incandescent lamp, the filament does not have to work "as hard" and filament life is increased. Because of its high intensity light characteristics, xenon is used in the aviation field for flashing lights guiding pilots on runway approaches. The latest innovation in automotive headlamps is the arc-discharge headlamp. Xenon flash lamps are used in lasers to "energize" or start laser lights. Though rapid advances in laser technology over the past two decades have provided numerous sources of pulsed coherent radiation throughout the infrared and visible spectrum, few high-power ultraviolet sources were commercially available until the discovery of the excimer laser, of which many use a xenon "flash" to get them started. Xenon and lasers are also finding possible application in wastewater treatment through generation of ultraviolet light. Current systems rely upon mercury vapour lamps. The xenon flashlamp, first developed as an energy source for laser beams, produces more photons and sends them out at energy levels five or more times intense than mercury devices. Xenon makes it possible to obtain better x-rays with reduced amounts of radiation and, when mixed with oxygen, is used to enhance contrast in CT imaging and to determine blood flow. Plasma display panels (PDPs) using xenon as one of the fill gases may soon replace the large picture tube in televisions and computer monitors. The advent of HDTV, along with the flat-panel PDPs promises to revolutionise the TV and computer display industry. Liquid xenon has been proposed for use in a calorimeter for sub-atomic particle detection. Many researchers around the world are involved in this research. As liquid xenon is roughly 500 times as dense as gases normally used in particle detectors, and its atoms are therefore more tightly packed, it promises to provide exquisite sensitivity and accuracy over 10 times greater than previous devices in pinpointing the positions of particles. Xenon is not actually consumed in the detection process, and is recycled, so, aside from the initial filling volume requirement, makeup losses for these types of devices are small. One of the newest fields to make its demands for xenon known is the aerospace industry. Although not a new idea, the use of xenon as a propellant for positioning thrusters on satellites has recently gained significant momentum. ARC-DISCHARGE HEADLAMPS These lamps are much smaller, last six times as long, and produce a whiter light. The bulbs are tiny - about the size of a match - and contain xenon and two tiny tungsten electrodes. Electricity jumps across the gap between the electrodes, producing a very intense white light. Because of its small size, the whole lamp assembly can be reduced to the size of a credit card. The result is better, more aerodynamic styling possibilities, along with significantly reduced weight, when compared to the glass assemblies in use currently. |
