ABSTRACT:
A method is provided for preparing medicinally acceptable .sup.123 I by bombarding an XI (X is alkali metal or I) target in the liquid phase with a proton beam of a predetermined amperage and energy, while continuously passing a helium stream, optionally having a small amount of xenon, through the target area. The radioactive xenon collected by the helium stream is trapped in a cold trap, purified and then isolated in a deacy vessel, where the xenon decays to .sup.123 I. An iodine scavenger is provided for the helium effluent from the target, to remove any iodine from the helium stream, which would decrease the purity of the desired isotope.
