This photo taken on March 3, 2014, and provided by the North Dakota Health Department, shows the exterior of an abandoned building in Noonan, North Dakota, where bags full of radioactive oil filter socks, the nets that strain liquids during the oil production process, were found. State Waste Management Director Scott Radig said the hundreds of the tubular filters discovered last week in the abandoned building is likely to be more than twice as large as the state's next-largest dumping incident found last month in McKenzie County.
