Supporting UNC Institutions

Radiation SafetyThe Radiation Safety section provides radiation safety services to other University of North Carolina system institutions that do not have the expertise to handle some program requirements or the budget to hire consultants. This benefits the UNC system with cost-savings realized by smaller campuses, as well as helping the smaller campuses maintain compliance with regulatory requirements. The ability to provide radiation safety services is requested for and approved by the regulatory agency through radioactive materials licenses. Additionally, the Radiation Safety staff provide expertise and support for issues regarding potential exposure to non-ionizing radiation.

In 2017, services were provided to Gateway University Research Park (UNC-G and NC A&T), Western Carolina, Appalachian State, UNC-Greensboro, UNC-Charlotte, NC A&T, UNC Pembroke, NCCU, UNC-TV and WUNC Public Radio. Services included radiation detector calibrations, X-ray machine surveys, radiation protection program reviews, laser safety program and training, radioactive materials disposal recommendations and risk communications to a childcare facility near a radio transmission tower.

Radiation detector calibration services covered as many as 38 survey meters, while program reviews require full audits of programs resulting in a report providing non-compliance items and recommendations for improvements. These types of reports are required of the other campuses by the North Carolina Radiation Protection Section. The UNC-Chapel Hill Radiation Safety staff is dedicated to supporting the University of North Carolina system.

Performance measurement is a critical part of the EHS management system. Education, customer service and internal processes are the three most essential components of our work. The chart below indicates the performance in these areas over a five-year period with Level Four representing optimum performance. The adjacent tab shows the specific performance activities and the level of that performance for 2017.
