A small robot is roving around a massive U.S. nuclear waste site to gather critical samples of potential air and water contamination after an emergency was declared Tuesday. The machine was deployed after a tunnel that stores rail cars filled with radioactive waste partially collapsed at Hanford Nuclear Reservation in Washington state. The mishap raised fears of a radiation leak at the nation's most contaminated nuclear site, though officials said there was no actual indication of a release of plutonium radiation as of 2:20 p.m. PDT. The air- and soil-sampling robot is monitoring for any changes on the scene. This robot is being used at Hanford right now to sample contamination in the air and on the ground.
