The present invention provides a positron source essentially consisting of a carbon member having F bound onto the surface thereof, a method of a 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 O and a small amount of natural fluorine ions with a beam of charged particles to generate F, and then passing an electric current through the solution using a carbon member as an anode to cause to bind the generated F onto the surface of the carbon member
