A representative of the
Iowa Bureau of Radiological Health reported a possible exposure event involving members of a medical center staff and perhaps others who were exposed to a patient that had recently been given a thyroid ablation treatment. The patient had been administered a dose of 150 millicuries of
I-131 to ablate the thyroid on 8/6/10. The patient was then released and cautioned on avoiding contact with other people. On 8/7/10, the patient experienced an medical condition that resulted in an incoherent condition and was rushed to a medical center for treatment of that condition. The medical center was unaware of the patient's recent
I-131 thyroid ablation treatment. The Radiology Group that administered the thyroid ablation subsequently became aware of the patient's admittance to the medical center. The Radiology Group is working with the medical center and also contacted the State of
Iowa with the concerns about exposure that general members of the public may have received from the thyroid patient.
The State does not know details on the radiation levels that were present near the thyroid patient at the time of this event. The State is investigating the details of the event and possible exposures. The State is uncertain if the event is reportable under the State equivalent of
10 CFR 35.75 assuming that the patient met the release criteria after the thyroid treatment at the Radiology Group.
