Members of the 79th Medical Wing and 11th Civil Engineer Squadron perform a "wet decontamination" upon returning from a simulated radioactive site as part of annual Black Flag training at the Center for National Response in Gallagher, W. Va, March 29. Prior to removing a hazardous material suite, all personnel that may have been exposed must decontaminate themselves in order to not spread radiation.
