Government investigators smuggled radioactive materials into U.S.

Two teams of government investigators using fake documents were able to enter the United States with enough radioactive sources to make two dirty bombs, according to a federal report made available Monday.

The investigators purchased a “small quantity” of radioactive materials from a commercial source while posing as employees of a fictitious company and brought the materials into the United States through checkpoints on the northern and southern borders, according to a Government Accountability Office report prepared for Senate Permanent Subcommittee on Investigations Chairman Norm Coleman, a Minnesota Republican.
