Aiming to plug the huge security hole that is our domestic port system, researchers at Sandia National Laboratories have developed a so-called "neutron-scatter" camera that is able to detect almost any radioactive material in its field of view -- even if it's hidden behind layers of shielding, such as in a cargo container. While traditional gamma ray-based handheld detectors are hobbled by relatively stringent proximity requirements, the Sandia cam uses an array of orthogonal sensors to pinpoint neutrons in 3D space at a "classified" distance, although its bulk and laggy
