Abstract
The present invention provides a positron source essentially consisting of a carbon member having .sup.18 F bound onto the surface thereof, a method of preparing the same, and an automated system for supplying the same. In the present invention, the positron source is prepared by irradiating a solution containing both H.sub.2.sup.18 O and a small amount of natural fluorine ions with a beam of charged particles to generate .sup.18 F, and then passing an electric current through the solution using a carbon member 40 as an anode to cause to bind the generated .sup.18 F onto the surface of the carbon member.
