Technical Capability Standards for Radiological Detection

The following publications establish technical capability standards for radiological and nuclear detection goals unique to the U.S. Government. The materials augment the national consensus standards established by American National Standards Institute (ANSI) and international consensus standards developed by the International Electrotechnical Commission (IEC).

Weapons of Mass Destruction

Weapons of Mass Destruction

The United States faces a rising danger from terrorists and rogue states seeking to use weapons of mass destruction.  A weapon of mass destruction is a nuclear, radiological, chemical, biological, or other device that is intended to harm a large number of people.  The Department of Homeland Security works every day to prevent terrorists and other threat actors from using these weapons to harm Americans.

IND Health and Safety Planning Guide

The Health and Safety Planning Guide for Planners, Safety Officers, and Supervisors for Protecting Responders Following a Nuclear Detonation provides response planners, safety officers, and supervisors with specific information and recommendations to protect responders from the effects and impacts of an extreme event: a 10 kiloton (KT) improvised nuclear device (IND) within the first 72 hours of a detonation.

DHS Announces Expansion of the Securing the Cities Program

WASHINGTON—The Department of Homeland Security (DHS) today announced the expansion of the Domestic Nuclear Detection Office’s (DNDO) Securing the Cities program to Houston and Chicago, further building upon the Department’s ongoing efforts to increase the Nation’s capabilities to detect and protect against radiological and nuclear threats. 

DNDO Commemorates 10 Year Anniversary within the Department

10 year anniversary coinToday, we commemorate the 10th anniversary of the Department of Homeland Security’s Domestic Nuclear Detection Office (DNDO). DNDO was established through presidential directive on April 15, 2005 with the singular mission to prevent nuclear terrorism through nuclear detection. In 2006, DNDO was tasked with the technical nuclear forensics mission. To accomplish our mission, DNDO collaborates with a wide range of partners and promotes innovative approaches to protect the nation. In fact, the Partnership for Public Service recently ranked DNDO # 2 for Innovation among 314 agency subcomponents, based on results from the 2014 Federal Employee Viewpoint Survey.

The National Technical Nuclear Forensics Ground Collections Task Force, pictured here, exercises its mission to collect nuclear debris samples near the site of a simulated nuclear detonation for analysis at designated laboratories. DNDO helps with the planning and execution of this and other nuclear forensics exercises.

Bolstering Nuclear Forensics to Prevent Nuclear Terrorism

Five years ago, President Obama signed into law an important piece of homeland security legislation designed to help protect our Nation against the threat of nuclear terrorism. The Nuclear Forensics and Attribution Act (NFAA) assigned to the Department of Homeland Security key nuclear forensics responsibilities and authorized the National Technical Nuclear Forensics Center within DHS’s Domestic Nuclear Detection Office (DNDO).
