Targetry and radiochemical methods for the simultaneous cyclotron production of no-carrier-added radiopharmaceutical-quality 100Pd, 97Ru and sup(101m)Rh

Target-dissolution and radiochemical methods were investigated to optimize the simultaneous production of radiopharmaceutical-quality, no-carrier-added (NCA) 3.63-d 100Pd, 2.88-d 97Ru and 4.26-d sup(101m)Rh. Metallic Rh (100% 103Rh) and RhCl3 x 3H2O were used as target materials. After bombardment with high energy protons these targets were subjected to a combination of procedures in order to separate the desired radionuclides. The use of a single cyclotron target in combination with several radiochemical processes were investigated to simultaneously produce these radionuclides in high-specific activities and radiochemical forms suitable for radiopharmaceutical syntheses.
