(University of Guelph) Studying radiation chemistry and electronic structure of materials at scales smaller than nanometres, the University of Guelph team prepared samples of clay in ultra-thin layers. Working at the TRIUMF particle accelerator, they bombarded the samples with antimatter subatomic particles. They found their system is a proven tool for radiation studies of material to be used to store nuclear waste — important for Canadian nuclear industry looking to build its first geological repository.
