Researchers from North Carolina State University have developed a new technique for determining the historical location and distribution of radioactive materials, such as weapons grade plutonium. The technique may allow them to use common building materials, such as bricks, as a three-dimensional "camera," relying on residual gamma radiation signatures to take a snapshot of radioactive materials even after they've been removed from a location.
