As many anticipated, the U.S. Government missed the July 1 deadline for ensuring that 100% of shipping containers bound for the United States are scanned for radioactive materials before they reach the United States. Certain 2007 amendments to the Security and. Accountability For Every Port (“SAFE Port”) Act of 2006 imposed this deadline, based on 9/11 Commission findings showing a vulnerability in detecting nuclear devices in shipping containers. Janet Napolitano, Secretary of the Department of Homeland Security, informed Congress in May that she would extend the deadline for meeting the 100% goal by two years. She said that such an extension was necessary due to the tremendous cost and burden of meeting the goal.
