The patient was scheduled for a red blood cell study. After injecting 21.1 mCi, the Tech noticed resistance and could not deliver the rest of the dose. A scan of the patient indicated the material was not metabolizing, and a localized spot was identified near the port. The Nuclear Medicine Physician, after reading the scan, determined that the dose had been delivered to a volume of 15-30 cubic centimeters of tissue around the port. The Radiation Safety Officer estimated that the committed absorbed dose to this tissue volume is on the order of 52.7 to 83.2 Rad, using MIRD dosimetry. The patient was notified by the Nuclear Medicine Physician, and the physician has indicated that there will be no deleterious effects on the patient. The NRC Operations Center was called at
