Preparation of intense 68Ga positron sources by electrocodeposition of 68GeCu3

Investigation of a new, high efficiency technique for the preparation of laboratory sources of 68Ga by electrocodeposition of 68GeCu3 from dilute alkaline cyanide baths is reported. Procedures are described which have resulted in stable and aherent plates of millicurie intensity. The specific activity of the material is shown to be a critical factor in producing thin (<= 1 mg/cm2) sources while achieving plating efficiencies in excess of 75%. (orig.)
