The National Science Foundation (NSF) awarded a $280,000 Project Grant under the Mathematical and Physical Sciences (CFDA 47.049) program to the University of Nevada, Las Vegas (UNLV) to develop a Quasi-Absolute Method (QAM) and 3-D isotopic imaging capabilities using neutron activation analysis. The project aims to advance the understanding and application of nuclear activation analysis and nuclear imaging across diverse scientific disciplines, with potential impacts in areas such as agriculture, industry, medicine, and the military. Key activities include optimizing QAM through neutron flux measurements and Monte Carlo simulations, validating the pulse activity equation, customizing NAA calculation software, and employing 3-D imaging reconstruction techniques to visualize isotopic distributions in samples. The project also provides valuable research training for underrepresented STEM students and develops online course materials on nuclear activation analysis. This award supports NSF's mission to promote the progress of mathematical and physical sciences and strengthen the nation's scientific enterprise.
