Domestic Nuclear Detection Office
The Global Nuclear Detection Architecture is a framework for detecting (through technical and non-technical means), analyzing, and reporting on nuclear and other radioactive materials that are out of regulatory control.
The Practical Arrangements build upon the extensive collaborative relationship between DHS and the IAEA, outlining the importance of strengthening nuclear security, and denoting four key areas for cooperation.
Helium-3 (3He) is a necessary component of many nuclear detection devices; however our country is facing a Helium-3 shortage. To address this shortage, DHS’ Domestic Nuclear Detection Office (DNDO) is advancing the search for efficient, cost-effective alternative technologies.
Last month, the Department of Homeland Security (DHS) Domestic Nuclear Detection Office (DNDO) completed final analysis on Helium-3 alternatives for neutron detection in radiation portal monitors, which are used to detect illicit radiological and nuclear materials.
