"A terrorist's use of a radiological dispersal device (RDD) or improvised nuclear device (IND) to release radioactive materials into the environment could have devastating consequences. GAO [Government Accountability Office] was asked to examine (1) the extent to which the federal government is planning to fulfill its responsibilities to help cities and their states clean up contaminated areas from RDD and IND incidents, (2) what is known about the federal government's capability to effectively clean up these contaminated areas, and (3) suggestions for improving federal preparedness to help cities and states recover from these incidents. The report also discusses recovery activities in the United Kingdom. GAO reviewed federal laws and guidance; interviewed officials from the Department of Homeland Security (DHS), Federal Emergency Management Agency (FEMA), Department of Energy (DOE), and Environmental Protection Agency (EPA); and surveyed emergency management officials from 13 cities at high risk of attack, their 10 states, and FEMA and EPA regional offices."
