Preparation of 99Mo from the 100Mo(γ, n) reaction and chemical separation of 99mTc

The radionuclide 99 Mo has been prepared by 100 Mo( γ , n ) reaction using two types of natural molybdenum compound (molybdenum trioxide and zirconium molybdate gel) with the bremsstrahlung end-point energies of 10 and 15 MeV. After the equilibrium, 99m Tc was separated as NaTcO 4 from the irradiate...

Description
Summary:The radionuclide 99 Mo has been prepared by 100 Mo( γ , n ) reaction using two types of natural molybdenum compound (molybdenum trioxide and zirconium molybdate gel) with the bremsstrahlung end-point energies of 10 and 15 MeV. After the equilibrium, 99m Tc was separated as NaTcO 4 from the irradiated samples using two different chemical procedures to examine the chemical yield. The separated Na[ 99m Tc]TcO 4 from the ZrMo gel has the 99Mo breakthrough of 99 % as well as chemical impurities of Al, Mo and Zr
