The Global Nuclear Detection Architecture

The Global Nuclear Detection Architecture detects and reports on radiological and nuclear materials that are out of regulatory control before they can be used in terrorist attacks.  It is comprised of a worldwide network of sensors, telecommunications, and personnel. 

Homeland Security Presidential Directive 14 and the SAFE Port Act of 2006 mandated the creation of the Global Nuclear Detection Architecture and charged the Domestic Nuclear Detection Office with coordinating its development and implementing its domestic component.  It is supported by the activities of the Department of Defense, Department of Energy, Department of Homeland Security, Department of Justice, and Department of State, as well as the U.S. Nuclear Regulatory Commission and the Office of the Director of National Intelligence, in coordination with state, local, and tribal authorities, international partners, and private entities.

Together, resources create a multi-layered defensive network to detect and assist interdiction of radiological and nuclear materials out of regulatory control, making it a truly global architecture.

Examples of the Global Nuclear Detection Architecture in action:

  • Radiation portal monitors scan for radiological and nuclear materials at international border crossings.
  • Law enforcement and public safety personnel employ radiation detectors to protect special events. 
  • U.S. Coast Guard teams carry radiation detection equipment when boarding vessels.
