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
