Abstract : The carrier-free radiopharmaceutical 43K as KCl was produced by the 44Ca (gamma, p) 43K reaction induced by bremsstrahlung radiation from an electron linear accelerator. An irradiation of one hour using 5.4 kW of 45 MeV electrons passing through a thick tantalum converter produced yields in excess of 1500 micro Ci per gram 44CaO. The 43K was separated from the target material and was prepared as 43KCl using ion-exchange chromatography. This radiopharmaceutical is now being prepared in millicurie quantities for myocardial imaging, electrolyte studies and other uses for which 40K and 42K are unsuited. (Author)
