A few micrograms of Mo-99 can produce enough Tc-99 to perform as many as 10,000 tests. Figure 20.12.2 20.12. 2: (a) The first Tc-99m generator (circa 1958) is used to separate Tc-99 from Mo-99. The MoO2−4 MoO 4 2 − is retained by the matrix in the column, whereas the TcO−4 TcO 4 − passes through and is collected.
