Educator Training

Unlocking the Invisible: An Introduction to Scintillators, Semiconductors, and Gamma Spectroscopy

September 19, 2024|6:00–7:00PM (7:00–8:00PM EDT)

All UsersAvailable to All Users



This webinar featured an exciting deep dive into the world of radiation detection! We explored the science behind scintillators and semiconductors, key components in detecting and measuring radiation. Through a live demonstration of gamma spectroscopy, participants gained an understanding of how these tools are used in fields ranging from medical imaging to environmental monitoring. View the above recording for an opportunity to see science in action and learn how these technologies help us explore the invisible forces around us.

Moderator

Mary Lou Dunzik-Gougar
Associate Dean of the College of Science and Engineering and Associate Professor of Nuclear Engineering at Idaho State University


Biographies

Amber Johnson

Amber Johnson is the director of the University of Maryland Training Reactor and holds a senior reactor operators license. She enjoys sharing the blue glow from her open-pool reactor with the many visitors who come for a tour each year. To share best practices across the United States research reactor community, Johnson serves as editor of a quarterly newsletter that tracks news, events, and regulatory items. Before joining the University of Maryland, she was an accelerator operator at the U.S. Department of Energy’s Fermi National Accelerator Laboratory.

Mary Lou Dunzik-Gougar

Mary Lou Dunzik-Gougar is the associate dean of the Idaho State University (ISU) College of Science and Engineering, associate professor of nuclear engineering and a senior reactor operator at ISU’s Aerojet-General Nucleonics nuclear reactor, commonly known as the AGN-201. Presently, she coordinates the nuclear engineering curriculum at ISU and teaches core graduate and undergraduate courses. She also performs nuclear materials research and is involved in regional and discipline accreditations, ISU’s international program development, and reactor administration.

Mary Lou has published internationally and is recognized as principal investigator of productive research projects incorporating nuclear material irradiation and characterization and the associated management of radioactive material.

She has collaborated on a variety of projects and proposals in university, national laboratory, and international research environments. This includes her work as a joint appointee scientist at Idaho National Laboratory where she led the Simulation Institute for Nuclear Enterprise Modeling and Analysis fuel-cycle modeling project. She also worked at Argonne National Lab with various duties associated with pyroprocessing spent fuel and was also a high school science and math teacher in the U.S. and U.K.

Mary Lou has a B.S. in chemistry from Cedar Crest College and received an M.S. in environmental engineering along with her Ph.D. in nuclear engineering from Pennsylvania State University. Her research interests include the nuclear fuel cycle, nuclear fuels and materials development, spent fuel processing, and waste form development.

An ANS member since 1992, Mary Lou was on the ANS Board of Directors from 1996-1999. She is a member of the Accreditation Policy & Procedures Committee; Development Committee; Fuel Cycle and Waste Management Division; Education, Training and Workforce Development Division; the Special Committee on Government Relations; and is the faculty advisor for the ANS Idaho State University Student Section. She is an active member of the Idaho ANS Local Section and has served on numerous organizing committees for local and national meetings.

In 2011 and 2014, she was the recipient of ANS Presidential Citations in addition to the Landis Public Communication and Education Award in 2014.
