School of Nuclear Science and Engineering instructor Lily Ranjbar (Ph.D. Oregon State, 2016), and Ph.D. candidates Steven Czyz (left) and Salam Alhawsawi are developing radioxenon detectors for nonproliferation purposes. 

How do you prove someone tested a nuclear weapon? Researchers Lily Ranjbar, Steven Czyz, and Salam Alhawsawi from the Radiation Detection Group in Oregon State's School of Nuclear Science and Engineering are developing devices that use the metallic alloy CZT to detect radioactive isotopes of the noble gas xenon. This helps prove if someone tested a weapon, supporting the Comprehensive Nuclear-Test-Ban Treaty (CTBT) that's been signed by 183 nation states.
