NEAR RICHLAND, Wash. -- Workers at Hanford have found contaminated soil that's being described as the most radioactive to date.
Crews found a steel liner had cracked under a drain in a building in the 300 area. Samples showed radiation levels thousands of times greater than allowable limits.
The Department of Energy says there's no sign the contamination has made it into groundwater. More sampling will be done in the days ahead.
Representatives for Washington Closure say there is no immediate danger to workers or the environment.
