In this report, F-18 radionuclide was produced from enriched-water target whereas Tc-99m was generated from natural molybdenum trioxide (MoO3) target. Two recoiled radioactive impurities such as Co-56 and Ag-110m are identified in the F-18 solution whereas N-13 was recognized as an impurity in the Tc-99m production. The Co-56 radionuclidic impurity is presumably sputtered off the havar window in the target system whereas Ag-110m is originally from a silver body housing the enriched water target which is generated by secondary neutron irradiated Ag-10⁹. In addition, N-13 impurity found in the post-irradiated MoO3 target occurs presumably via (p,He-4) nuclear reaction.
