Common Bricks Can Be Used to Detect Past Presence of Uranium, Plutonium
Researchers from North Carolina State University have demonstrated a technique that can determine whether bricks – the common building material – have ever been near a radiological source, and identify the specific type of source, such as high enriched uranium or plutonium. The technique is possible when there are no chemical residues left behind, and has security and nuclear nonproliferation applications. (more…)
