title: Contamination of the packing material of sodium iodide (131I) therapy capsules with an unexpected radionuclide.
abstract: All of the packing inside the metal transport cylinder of some sodium iodide (131I) therapy capsules, especially the filling material surrounding the lead container, was found to be contaminated with 131mXe, a daughter radionuclide of 131I. Therefore, users should open the containers only under a well-ventilated hood.
