Xenon
—
133
Ventilation
Scans
Xenon is used for pulmonary ventilation scans. It shows how air moves in and out of the lung. This isotope is advantageous in that its 5.27 day half-life allows Xenon to be shipped without much loss of radioactive decay. Xenon—133 is being used as an inhalation method and can be administered safely due to its short biological half-life.
