The Radiation Safety Office (RSO) administers eight radioactive materials licenses and 21 X-ray registrations covering approximately 330 radiation producing imaging devices for UNC and UNC Medical Center. The licenses are issued by the Radioactive Materials Branch of the NC Radiation Protection Section (NC-RPS) while the registrations are issued by the X-ray Branch of the NC-RPS. The NC-RPS is housed in the NC Department of Health and Human Services, Division of Health Service Regulation.
As part of their mission, the NC-RPS inspects their licensees and registrants on a routine basis to ensure that regulatory requirements are met for safe use of radioactive materials and radiation producing machines. In FY 2016, the RSO experienced an unprecedented 19 inspections. The high number of inspections was because the NC-RPS recently become fully staffed and had to “catch up” on inspections that had not been done in years.
The RSO hosted five radioactive materials license inspections and 14 X-ray registration inspections. The intensity of these inspections varied widely in the number of inspectors involved (as few as one and as many as five), in the number of days the inspection took place (as few as one and as many as four), and in the scope of the inspection (as few as one machine and as many as 109).
Of the many inspections that took place, only one materials license inspection resulted in a documentation citation which was quickly and easily resolved. Only one X-ray registration inspection yielded citations, all of which were quickly and easily resolved to the satisfaction of the NC-RPS. This particular X-ray registration included 109 imaging devices and had not been inspected in more than 15 years. Although these inspections require a lot of resources from the RSO staff, they also demand that UNC and UNC-MC maintain a high quality and compliant program to ensure the safe use of radioactive materials and radiation producing machines for teaching, research, and public service.
The Radiation Safety Office (RSO) worked with the Physics department staff to support the implementation of these custom-made devices by registering these x-ray sources which are not commercially available and are more complex than typical devices to register with the NC-RPS. The RSO utilized monitoring equipment in non-traditional ways to do scatter and/or leakage surveys because these are non-traditional sources of x-rays.
