Photonuclear Production of Potassium-38,
Abstract
Radioactive potassium-38 has been produced by the photonuclear reactions 39K (gamma,n) 38K and 40Ca (gamma,np) 38K using the bremsstrahlung field developed by an electron linear accelerator. Noncarrier-free 38K was produced by irradiating potassium hydroxide pellets for 30 minutes using 10 kW of 40 MeV electrons passing through a thick tantalum converter. Yields of 50-70 mCi 38K per gram KOH irradiated were obtained. Carrier-free 38K was produced by similarly irradiating shredded calcium metal, obtaining 1-3 mCi per gram of calcium. In both cases, the target material was dissolved in HCl, neutralized and prepared as sterile solutions of KCl for injection.
