WebIodine-123 is produced in a cyclotron by bombardment of enriched xenon-124 by the (p,2n) reaction via the shorter lived caesium-123 and xenon-123. The energy of the γ-ray emission (159 keV) is close to the ideal for imaging using gamma cameras. Several different iodination methods are employed to synthesise radiolabelled iodine-123 compounds.
