NICK CONTOS USES DETECTOR TO MEASURE RADIATION DURING TERRORISM RESPONSE EXERCISE, 2003-05-13 (photo)

Nick Contos (R) uses a detector to measure potential radiation on Charles Mansfield during an exhibition of how teams would respond to a terrorist attack that used radioactive material, during a media preview at the Joint Information Center in Argonne, Illinois, May 13, 2003. Against the backdrop of a deadly attack on Americans in Saudi Arabia, emergency workers in two U.S. cities combated simulated bomb and biological terrorism on Tuesday as the government mounted the largest security exercise of its kind. In contrast to the bombast marking the $16 million drill's beginning in Seattle on Monday, where a supposed radioactive "dirty bomb" was set off with pyrotechnics, Chicago's simulated attack was a silent germ warfare invasion that sent the first of hundreds of "patients" to hospitals.
