Dr. Fjeld's major teaching and research interests are in the environmental aspects of nuclear technologies. He teaches courses in radiation and health physics, radioactive waste management, radiation measurements, and risk assessment. He developed a course in Environmental Risk Assessment which he taught for more than 25 years. He is lead author of a textbook, Environmental Risk Analysis for Human Health, based on the instructional materials he developed for the course. Current research interests are focused on the transport and measurement of radionuclides in the environment, with a specific emphasis on the behavior and sub-surface transport of radionuclides at Department of Energy sites.
Dr. Fjeld does not currently teach classes.
