ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

Colin Judge: Testing structural materials in Idaho’s newest hot cell facility
Idaho National Laboratory’s newest facility—the Sample Preparation Laboratory (SPL)—sits across the road from the Hot Fuel Examination Facility (HFEF), which started operating in 1975. SPL will host the first new hot cells at INL’s Materials and Fuels Complex (MFC) in 50 years, giving INL researchers and partners new flexibility to test the structural properties of irradiated materials fresh from the Advanced Test Reactor (ATR) or from a partner’s facility.
Materials meant to withstand extreme conditions in fission or fusion power plants must be tested under similar conditions and pushed past their breaking points so performance and limitations can be understood and improved. Once irradiated, materials samples can be cut down to size in SPL and packaged for testing in other facilities at INL or other national laboratories, commercial labs, or universities. But they can also be subjected to extreme thermal or corrosive conditions and mechanical testing right in SPL, explains Colin Judge, who, as INL’s division director for nuclear materials performance, oversees SPL and other facilities at the MFC.
SPL won’t go “hot” until January 2026, but Judge spoke with NN staff writer Susan Gallier about its capabilities as his team was moving instruments into the new facility.
2020 ANS Virtual Winter Meeting Plenary Special Session Speaker
Kansas State University
Amir Bahadori earned Bachelor of Science degrees in Mechanical Engineering with Nuclear Engineering Option and Mathematics from Kansas State University in 2008. He then attended graduate school at the University of Florida, graduating in 2010 with a Master of Science degree in Nuclear and Radiological Engineering and in 2012 with a Doctor of Philosophy degree in Biomedical Engineering. Bahadori worked as a contractor for NASA Johnson Space Center from 2010 to 2013 and then as a civil servant from 2013 to 2015, with work focused on astronaut radiation risk projection and assessment, space radiation dosimetry using active pixel detectors, and space radiation transport using deterministic and Monte Carlo-based codes. He returned to Kansas State University as an assistant professor in December 2015, where he teaches courses related to nuclear and radiological engineering and conducts research with focus areas in space radiation protection, radiation transport applications, and semiconductor detector modeling and simulation. Since 2015, Bahadori has been certified in the comprehensive practice of health physics by the American Board of Health Physics. In addition to ANS membership, he is a member of the Health Physics Society, International Radiation Physics Society, and the IEEE Engineering in Medicine and Biology Society. Bahadori is also an associate of the Committee on Space Research of the International Council for Science.
