Designed to detect trace amounts of radiation, it's a battery-powered, lunch-box-size handheld detector that customs officers could use to inspect suspicious containers at close range. Bruce Goodwin, head of the lab's nuclear-weapons program, says he hopes to see future versions of the device no bigger than a pen and "cheap enough so that every cop can have...
