Separation And Purification Of Tc-99m From Mo-99 Produced By Electron Linear Accelerator

The medical radionuclide Mo-99 was produced by the Mo-100(gamma,n) reaction using bremsstrahlung photons generated by an electron linear accelerator. The amount of Mo-99 produced was compared to that predicted by calculation using the particles and heavy ion transport code system. From the Mo-99 produced, highly pure Tc-99m was separated using the so-called technetium master milker, and the chemical yield of Tc-99m was 83-99 %. The installation of a new complex using this method and the electron linear accelerator with the preferable specification was suggested, and a possibility to supply the demand of Tc-99m was discussed and shown.
