Abstract
For tile rapid production of fluorine-18 for medical use, the up-to-date methods of separation such as the recoil separation, the alumina column chromatography, and the distillation are reviewed. The amount of the residue, the gamma emitting impurity, and the tritium content in the product obtained by each separation method are determined. The product obtained by the nuclear recoil separation or by the alumina column chromatography is inferior to that obtained by the distillation in the purity point of view. Thus, the separation by the distillation is tile most effective especially in the case of using a natural lithium carbonate target. Carrier free fluorine-18 of about 2 mCi can routinely be produced by irradiating 7g of the natural lithium carbonate under the neutron flux of about 1
