5. Health Physics Surveillance The pmpose of Health Physics surveillance is to ensure safe use of radioactive materials in the Nuclear Science Center's research and service activities and to fulfill the regulatory requirements of tlie U.S. Nuclear Regulatory Commission and State agencies. The NSC maintains a Health Physics group as an integral part of the organization. It is responsible for radiological as well as chemical and physical safety concerns. The radiation safety team at the T AMU Environmental Health and Safety Department provides a~ditional support to the NSC Health Physics group upon request.

5.1 Personnel Monitoring Personnel Monitoring was provided on a monthly basis to approximately 48 personnel. All measured doses. to personnel were below the limits set forth in 10 CFR 20. The highest deep dose equivalent (DDE) recorded was 0.607R for the year. Airborne monitoring during-sample handling continued to show no significant airborne activity, therefore, total effective dose equivalent will equal deep dose equivalent for 2019. During 2019, 691 visitors toured the Nuclear Science Center. Minimal exposures were measured with pocket ion chambers worn by these visitors and the pocket ion chamber readings of their respective tour guides. NSC employees who were likely to exceed 10% of their total annual dose wore whole body badges (Luxel dosimeter) and extremity badges (TLD dosimeters) that were provided by Landauer, a NVLAP accredited supplier. Landauer al~o provides the reports of the doses,:i;eceived. Employees who potentially handle more radioactive materials on a regular basis were provided two extremity badges and were exchanged on a monthly basis. 5.2 Facility Monitoring Surveys of the Nuclear Science Center facilities were performed to assess radiological hazards to NSC workers. Radiation levels and sources* of radioactive contamination were routinely monitored. All areas accessible to the general public at the NSC were surveyed for radiation and contamination levels monthly by ion chamber readings. and evaluation of smear samples. Areas where contamination is expected are access/egress controlled and are evaluated on shorter intervals as needed. Building monitors and Area monitors are located strategically throughout the reactor facility, providing dose equivalent (mrem) on a monthly basis._ Table 5-2 summarizes the annual* accumulated dose equivalent (mrem) recorded on the area monitors for foe year 2019. 8
