A radiological attack is the spreading of radioactive material with the intent to do harm. Radioactive materials are used every day in laboratories, medical centers, food irradiation plants, and for industrial uses. If stolen or otherwise acquired, many of these materials could be used in a "radiological dispersal device" (RDD).
The U.S. Department of Homeland Security and The National Academies teamed up in 2003 to produce fact sheets on chemical, biological, radiological, and nuclear attacks designed to help better prepare the media for the types of threats facing the nation.
Each fact sheet provides clear, concise information to the media and the public on the characteristics, dangers, and consequences associated with various types of attacks. Each fact sheet has been through a rigorous peer review process evaluated by independent members of the National Academies, many of whom are recognized as the nation's foremost experts in their field.
