Combating Nuclear Smuggling: Corruption, Maintenance, and Coordination Problems Challenge U.S. Efforts to Provide Radiation Detection Equipment to Other Countries, Report to Congressional Requesters [open pdf - 6MB]
"According to the International Atomic Energy Agency, between 1993 and 2004, there were 662 confirmed cases of illicit trafficking in nuclear and radiological materials. Three U.S. agencies, the Departments of Energy (DOE), Defense (DOD), and State (State), have programs that provide radiation detection equipment and training to border security personnel in other countries. GAO examined the (1) progress U.S. programs have made in providing radiation detection equipment to foreign governments, including the current and expected costs of these programs; (2) challenges U.S. programs face in this effort; and (3) steps being taken to coordinate U.S. efforts to combat nuclear smuggling in other countries."
