On September 21, 2011, the NRC issued a Notice of Violation to Associated Specialists, Inc. (ASI), for a Severity Level III problem. The violations involved the licensee’s failure to: (1) limit operation with a temporary radiation safety officer (RSO) to a period of 60 days, in accordance with 10 CFR 35.24(c); and (2) ensure that its authorized user (AU) provided adequate supervision to licensee staff who were involved in the receipt, possession, use, transfer or preparation of byproduct material, in accordance with 10 CFR 35.27. Specifically, after ASI’s RSO left the company on June 8, 2010, the AU functioned as the temporary RSO until October 13, 2010, a period greater than 60 days. And from August 16, 2009 until April 19, 2011, the AU had limited oversight of the program, such that ASI personnel under the supervision of the AU had not spoken to him and had not received instructions associated with ASI’s written radiation protection procedures, NRC regulations, ASI’s license conditions, and the requirement that supervised individuals follow the instructions of the supervising authorized user for medical uses of byproduct material.
