Radiological Dispersal Devices: An Initial Study to Identify Radioactive Materials of Greatest Concern and Approaches to their Tracking, Tagging and Disposition. Report to the Nuclear Regulatory Commission and the Secretary of Energy [open pdf - 202KB]
"The events of September 11, 2001, heightened the nations concerns regarding the use of radioactive materials for a malevolent act. In June 2002, the Secretary of Energy and the Chairman of the Nuclear Regulatory Commission (NRC) met to address these concerns and discuss the nations ability to adequately protect inventories of nuclear materials that could be used in a radiological dispersal device (RDD). An attack involving an RDD has been of particular concern because of the widespread use of radioactive materials in the United States and abroad by industry, hospitals, and academic institutions. At the June meeting, the Secretary of Energy and the NRC Chairman agreed to convene an Interagency Working Group on Radiological Dispersal Devices (hereafter WG) to address these concerns. In the first meeting, the WG identified the following four focus areas for examination: (1) the relative hazards of radioactive materials; (2) the options for establishing a national source tracking system; (3) the potential for the use of technological methods for tagging and monitoring sources while in use, storage and transit; and (4) actions for facilitating the securing and final disposition of unsecured, excess, and unwanted sources."
