Researchers have developed a 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.
