Dirty Bomb Vulnerabilities: Staff Report, Permanent Subcommittee on Investigations, United States Senate [open pdf - 1MB]
"Since 2003, the U.S. Senate Permanent Subcommittee on Investigations ('PSI' or the 'Subcommittee') has engaged in a bipartisan investigation into U.S. government efforts to prevent a nuclear or radiological attack on U.S. interests. The Subcommittee's efforts have included oversight investigations into U.S. port security and global supply chain security. In addition, PSI has, with the assistance of the U.S. Government Accountability Office (the 'GAO'), probed certain vulnerabilities in the U.S. government's practices and procedures for issuing licenses to possess radiological materials. This report is another component in that effort, examining certain vulnerabilities in U.S. regulation of radiological materials and whether America's enemies could exploit those weaknesses to develop a so-called 'dirty bomb.' Finally, this report presents certain recommendations to remedy those vulnerabilities."
