What are some properties of 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.
How is Xenon 133 used?
Xenon Xe 133 gas is used to help diagnose lung problems and to help your doctor see an image of your lungs. It is also used to help your doctor check the blood flow in your brain. This medicine is to be given only by or under the direct supervision of a doctor with specialized training in nuclear medicine.
What is Xenon gas used for medically?
In medicine, Xenon can be utilized as a neuroprotective and anesthetic agent. It can also be used as a contrast agent in imaging. Plus it has the potential to be used in the field of optics. In vitro and in vivo studies prove that Xenon has therapeutic effects on various neurodegenerative outcomes.
What is the biological half life of xenon-133?
5.245 days
PHYSICAL CHARACTERISTICS Xenon Xe 133 decays by beta and gamma emissions with a half-life of 5.245 days.
What are the benefits of xenon-133?
Xenon-133 is an inhaled radiopharmaceutical imaging agent primarily used to image the lungs and evaluate pulmonary function. It may also be used to assess cerebral blood flow. Xenon-133 Gas is inhaled to provide diagnostically relevant images of the lungs to physicians.

Who discovered xenon 133?
Xenon was discovered by Sir William Ramsay, a Scottish chemist, and Morris M. Travers, an English chemist, on July 12, 1898, shortly after their discovery of the elements krypton and neon. Like krypton and neon, xenon was discovered through the study of liquefied air. The earth’s atmosphere is about 0.0000087% xenon.
What are the advantages of xenon-133?
At present, 133 Xe is the most widely available method. Advantages are established safely, availability of normal values, reasonable cost effectiveness, and wide applicability. Disadvantages are poor resolutions and errors due to lack of knowledge of solubility of xenon in abnormal tissues.
What are the advantages of xenon 133?
How do you make xenon 133?
Xenon Xe 133 is produced by fission of Uranium U 235. At the time of calibration, it contains no more than 0.3% Xenon Xe 133m, no more than 1.5% Xenon Xe 131m, no more than 0.06% Krypton Kr 85 and no more than 0.01% Iodine I 131, with no less than 99.9% total radioactivity as radioxenon.
What is the biological half life of xenon?
PHYSICAL CHARACTERISTICS Xenon Xe 133 decays by beta and gamma emissions with a half-life of 5.245 days. which are emitted by the nuclide are listed in Table 1.
Is xenon Xe 133 a radioactive gas?
Xenon Xe 133 is chemically and physiologically related to elemental Xenon, a non-radioactive monoatomic gas which is physiologically inert except for anesthetic properties at high doses. PHYSICAL CHARACTERISTICS Xenon Xe 133 decays by beta and gamma emissions with a half-life of 5.245 days.
Can xenon Xe 133 gas be used for cerebral flow assessment?
Inhalation of Xenon Xe 133 Gas has proved valuable for the evaluation of pulmonary function and for imaging the lungs. It may also be applied to assessment of cerebral flow. None known.
What is xenon133 used for in medicine?
