Why old nuclear-site concrete could become a tool for trapping strontium-90

Crushed concrete from legacy nuclear facilities could play a far greater role in safely managing radioactive land than previously understood. Research published in ACS ES&T Water and conducted by scientists from the University of Manchester, United Kingdom National Nuclear Laboratory and Clemson University has examined how crushed concrete interacts with strontium-90, a mobile radioactive contaminant found at nuclear legacy sites such as Sellafield and Hanford.
