Separation and purification of .sup.99mTc from .sup.99Mo produced by electron linear accelerator

The medical radionuclide .sup.99Mo was produced by the .sup.100Mo([gamma],n) reaction using bremsstrahlung photons generated by an electron linear accelerator. The amount of .sup.99Mo produced was compared to that predicted by calculation using the particles and heavy ion transport code system. From the .sup.99Mo produced, highly pure .sup.99mTc was separated using the so-called technetium master milker, and the chemical yield of .sup.99mTc 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 .sup.99mTc was discussed and shown.
