Accountability Office, 441 G St., NW, Rm. LM, Washington, D.C. 20548."GAO-08-979."Includes bibliographical references.The Department of Homeland Security's (DHS) Domestic Nuclear Detection Office (DNDO) is responsible for addressing the threat of nuclear smuggling. Radiation detection portal monitors are part of the U.S. defense against such threats. In 2007, Congress required that funds for new advanced spectroscopic portal (ASP) monitors could not be spent until the Secretary of DHS certified that these machines represented a significant increase in operational effectiveness over currently deployed portal monitors. In addition to other tests, DNDO conducted the Phase 3 tests on ASPs to identify areas in which the ASPs needed improvement. GAO was asked to assess (1) the degree to which the Phase 3 test report accurately depicts the test results and (2) the appropriateness of using the Phase 3 test results to determine whether ASPs represent a significant improvement over current radiation detection equipment.Combating Nuclear SmugglingRadioactive substancesDetectionTestingSmugglingUnited StatesPreventionNuclear terrorismUnited StatesPreventionNuclear countersTestingRadioactive substancesDetectionTesting.SmugglingPrevention.Nuclear terrorismPrevention.Nuclear countersTesting.DIDDIDGPODOCUMENT9910698693403321Combating nuclear smuggling3424817UNINA
