Two DNDO members participate in nuclear forensics exercise.

U.S. and Canada Hold First Joint Nuclear Forensics Exercise

The United States and Canada recently held the first joint nuclear forensics exercise between the two countries, in Halifax, Nova Scotia, Canada.  The exercise simulated a nuclear detonation, allowing experts from both countries to improve operational readiness to respond to radiological or nuclear attacks.  The advancement of international cooperation in nuclear forensics will help improve the ability of the U.S. and its allies to determine the source of a detonated device.

DHS Participates in Exercise Demonstrating New Nuclear Forensics Technology

Recently, the Domestic Nuclear Detection Office (DNDO) helped plan and conduct an exercise of the United States’ capability to collect radioactive evidence in the immediate aftermath of a nuclear detonation. The exercise scenario included the detonation of an Improvised Nuclear Device in an urban setting. In a real event, the evidence collected helps identify the source of the device and those responsible for its use.

DNDO Supports the Nuclear Security Summit

The Domestic Nuclear Detection Office’s (DNDO) efforts in nuclear forensics and detection were highlighted at the fourth Nuclear Security Summit in Washington, D.C. from March 31 to April 1, 2016.  The Nuclear Security Summit has focused international efforts to address nuclear terrorism since it was launched by President Obama in 2010.

Detecting Threats through "Nuclear Street View": The United States and Singapore Work Together to Strengthen Nuclear Security

Last month, the Domestic Nuclear Detection Office (DNDO) conducted a joint trial with Singapore’s Ministry of Home Affairs to assess the U.S.-developed Radiological Multisensor Analysis Platform system. This trial marks an important milestone in what has been a successful research and development collaboration between Singapore and the United States.  The collaboration has led to the advancement of capabilities to detect, identify, and localize radiological and nuclear threats.

New Technology Within the U.S. to Aid Nuclear Forensics

Last month, the Idaho National Laboratory hosted a ribbon-cutting ceremony for a newly operational radioisotope mass separator (RMS), a device that will improve the accuracy and precision of nuclear forensics analysis.
