On October 31, 2017, the NRC issued a Notice of Violation to Michiana Hematology Oncology, PC, for a Severity Level III problem relating to NRC licensing requirements. The violations involved: (1) the failure to have an individual named on the license perform the duties and responsibilities of Radiation Safety Officer (RSO) for the period of October 29, 2016, to April 16, 2017, as required by License Condition No. 11 of NRC License No. 13-32719-01; and (2) the failure to notify the NRC no later than 30 days after the RSO permanently discontinued performance of duties under the license as required by Title 10 of the Code of Federal Regulations, Section 35.14(b)(1). Specifically, the RSO listed on the license left the licensee's employment on October 28, 2016, and Michiana Hematology Oncology did not notify the NRC of this fact until January 25, 2017, when it requested an amendment to its license to change the RSO. The license was later amended to name a new RSO on April 18, 2017.
