a The first Tc-99m generator circa 1958 is used to separate Tc-99 from Mo-99. The MoO 4 2-is retained by the matrix in the column, whereas the TcO 4 . passes through and is collected. b Tc-99 was used in this scan of the neck of a patient with Graves disease. The scan shows the location of high concentrations of Tc-99.
