On September 3, 2013, the NRC issued a notice of violation to Maui Memorial Medical Center for a SL III violation involving the failure to implement 10 CFR 35.40(a) and related conditions of its license when it failed to ensure that the written directive was dated and signed by an authorized physician user before administering sodium iodine (I-131) at greater than 1.11 megabecquerels (30 microcuries). Specifically, on October 31 and November 21, 2012, for a total of three occasions, the licensee allowed a physician that was not listed as an authorized user on the license to sign a written directive for the administration of 5 millicuries of I-131 for diagnostic use.
