RADIOPHARMACEUTICAL PHYSICAL HALF-LIFE (MIN) 110 2.05 F-18-FDG or fluorodeoxyglucose 0-15-carbon dioxide or 0-15-carbon monoxide C-11-acetate or C-11-carbon monoxide or C-11-carbon dioxide N-13-ammonia 20.4 10 Radiopharmaceutical Engineering Mo-99 (t 2 = 66 hours) and Tc-99m (t12= 6 hours) are in transient equilibrium in a Mo generator. If 1000 MBq of Mo-99 is present in the generator, what would be the activity of Tc-99m after 82 hours, assuming that 87% of Mo-99 decays to Tc-99m
