Anything that hops, burrows, buzzes, crawls or grazes near a nuclear weapons plant may be capable of setting off a Geiger counter. And at the Hanford nuclear reservation, one of the dirtiest of them all, its droppings alone might be enough to trigger alarms.
A government contractor at Hanford, in south-central Washington State, just spent a week mapping radioactive rabbit feces with detectors mounted on a helicopter flying 50 feet over the desert scrub. An onboard computer used GPS technology to record each location so workers could return later to scoop up the droppings for disposal as low-level radioactive waste.
