On September 15, 2020, the NRC issued a Notice of Violation and Proposed Imposition of Civil Penalty in the amount of $7,500 to St. Luke’s Regional Medical Center (Licensee) for a Severity Level III problem associated with three related violations. The violations involved the licensee's failure to: (a) monitor occupational exposure of workers from licensed and unlicensed sources of radiation as required by Title 10 of the Code of Federal Regulations (10 CFR) 20.1502(a)(1); (b) develop and implement certain elements of its radiation protection program in accordance with 10 CFR 20.1101(a); and (c) provide instructions to individuals in accordance with 10 CFR 19.12(a)(3). Specifically, from January 1, 2012, to February 24, 2020, the licensee did not properly monitor interventional radiology (IR) physicians whose occupational exposure exceeded the NRC’s annual radiation exposure limit over the course of 8 years and did not develop and implement a radiation protection program commensurate with the scope and extent of its licensed activities. Additionally, the licensee did not provide instructions regarding radiation safety involving the proper use and storage of dosimeters to four IR physicians who were likely to receive an occupational dose in excess of the required annual limit.
