Three U.S. Senators have objected to the Department of Homeland Security's expansion of the airport body scanner program. In a letter to DHS Secretary Janet Napolitano, Senators Collins (R-ME), Burr (R-NC), and Coburn (R-OK) have asked "why the Department continues to purchase this technology when legitimate concerns about its safety appear to remain unanswered." The Senators noted that "the issue of radiation associated with the backscatter x-ray AIT machines has not been adequately addressed by TSA." They urged the agency's Chief Medical Officer, working with independent experts, to conduct a review of the health effects on travelers and airport personnel. EPIC recently submitted a FOIA request to the DHS for all records of tests conducted by the agency regarding radiation impacts. EPIC has also filed an emergency motion in federal court to suspend the program, pending an thorough review of the airport body scanner program.
