Absolute standardization of the impurity super(121)Te associated to the production of the radiopharmaceutical super(123)I

super(123)I is widely used for radiodiagnostic procedures. It is produced by reaction of super(124)Xe (p,2n) super(123)Cs arrow right super(123)Xe arrow right super(123)I in cyclotrons. super(121)Te and super(125)I appear in a photon energy spectrum as impurities.

Description
Summary:super(123)I is widely used for radiodiagnostic procedures. It is produced by reaction of super(124)Xe (p,2n) super(123)Cs arrow right super(123)Xe arrow right super(123)I in cyclotrons. super(121)Te and super(125)I appear in a photon energy spectrum as impurities. An activity of super(121)Te was calibrated absolutely by sum-peak method and its photon emitting probability was estimated, whose results were consistent with published results.
