The Department of Energy fined the Lockheed Martin Idaho Technologies Company for violating nuclear safety regulations. “The violations occurred in July 1996 when five workers in the INEEL [Idaho National Engineering and Environmental Laboratory] Waste Calcining Facility received unplanned internal radiation exposures. A worker cutting into a pipe caused airborne radiological contamination to be spread throughout the room. The workers, unaware of the airborne contamination and unprotected by respirators, remained in the contaminated environment for approximately 40 minutes.”
