Research Abstract |
To combat the Mo-99/Tc-99m crisis in Japan, we are proposing a small-scale direct Tc-99m production by using a medical cyclotron. We developed an automated Tc-99m production system with satisfaction of both easy-operability and low radiation exposure during the process including target preparation. The Tc-99m yield reached to about 6 to 8 mCi/micro-Ah at the end of bombardment, and [Tc-99m]TcO4- with >99% radiochemical purity was successfully obtained within 75 min by using two chelating-columns purification. The cyclotron-based Tc-99m production method has a potential to be an alternative of the conventional reactor-based Mo-99/Tc-99m supply.
