Nuclear Engineering Colloquium: Zaijing Sun
Title: "Applying Nuclear Activation Analysis on Agriculture Products and Environmental Monitoring."
Nuclear Activation Analysis (NAA) is a multi-elemental radioanalytical technique that has high accuracy, precision, and sensitivity. It generally includes photon activation analysis and neutron activation analysis according to the irradiation sources. To make this active nuclear assay more attractive and more competitive, we scrutinized the underlying nuclear physics, simulated the particle flux with Monto Carlo codes, derived a new activity equation for pulsed irradiation, discussed the feasibility of the quasi-absolute method, and implemented an online computer program to facilitate the calculations. To describe its applications in the real world, we discussed several cases involving agricultural products, food toxicology, and environmental monitoring. All the studies have led to some interesting results and demonstrated the promising future of this technology.
Zaijing Sun is an assistant professor in the Nuclear Engineering Program at South Carolina State University (SCSU). Before joining SCSU, he was a postdoc in the Nuclear Engineering Division at the Argonne National Laboratory. His research interests include nuclear activation analysis, health physics, environmental toxicology, radiochemistry, gamma-ray spectroscopy, Monte Carlo simulations, and Temporal Data Mining (TDM) in nuclear engineering.
