The process of the present invention includes preparing a first aqueous solution of rhenium in the form of radioactive perrhenate, wherein the concentration of rhenium in said solution is within the range of about 5x10-6M to about 2x10-3M, and then reducing and complexing the radioactive perrhenate by mixing a second solution or lyophilized solid with the first solution. The second solution or lyophilized solid comprises a ligand which complexes with the radioactive perrhenate and a reductant wherein the reductant is present in the second solution at a concentration in the range of about 0.005M to about 0.020M and the ligand is present in the second solution at a concentration in the range of about 0.01M and about 0.15M. The pH of the resultant solution is within the range of about 1.5 to about 5.5.
