While we're likely still quite a ways away from having nuke detectors in every cellphone, the Department of Homeland Security is apparently at least making some progress in other somewhat portable options, with it now showing off a radiation-hunting Chevy Suburban XL built with a little help from Raytheon. Intended specifically for the DHS's Domestic Nuclear Detection Office, the SUV boasts two sliding panels that can swing out for maintenance but remain neatly concealed when on duty, as opposed to current systems that are mounted in the back of pick-up trucks. That, of course, gets paired with a laptop, which provides a full spectroscopic analysis, and the entire system can be configured to trigger a number of different alarms, including a simple vibration alert to a dedicated PDA, or a scare-the-wits-out-of-everyone approach that involves setting off the car alarm, lights, horn and siren.
