A great number of radiopharmaceuticals have been labeled using I-123 and the number is increasing. One of the most promising uses of I-123 is in the imaging of monoclonal antibodies to localize and visualize tumors.
Web1 nov. 2014 · Abstract and Figures. Iodine-131 was generated by irradiation of natural tellurium dioxide in a nuclear reactor. After irradiation the tellurium dioxide was transferred to hot cell and heated in a ... 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.
