Elevated levels of uranium in water supplies is an environmental safety and health concern, but current methods of detecting it are cumbersome, costly and time consuming. Gary C. Tepper, Ph.D., chair of the Department of Mechanical and Nuclear Engineering, and Ph.D. student Brandon Dodd are addressing this challenge with a novel portable device that streamlines and expedites the way uranium in water is measured. Because their patented technology is more sensitive than current technologies, it is able to detect low or trace concentrations of uranium in water supplies.
