## Description

On March 4, 2011, the NRC issued a Notice of Violation to Oakwood Hospital – Annapolis Center for a Severity Level III problem involving: (1) the licensee's usage of a dose that differed from the prescribed dose by more than 20 percent which is contrary to 10 CFR 35.63(d); and (2) the failure to verify that the assayed dosage was within 10 percent of the prescribed activity as required by License Condition 15.A. Specifically, the licensee administered approximately 124.5 millicuries of sodium pertechnetate technetium-99m (Tc-99m) to a patient instead of the prescribed dosage of 10 millicuries of Tc-99m tetrofosmin, a difference in excess of 20 percent. The licensee failed to verify that it had the correct syringe which resulted in the incorrect radiopharmaceutical and dosage being administered to the patient.
