Department of Homeland Security 'Domestic Nuclear Detection Office' Budget Overview (Fiscal Year 2018 Congressional Justification) [open pdf - 2MB]
From the Document: "The Domestic Nuclear Detection Office (DNDO) requests $330.440 million, 158 positions, and 144 FTEs [full-time employees] in FY 2018. DNDO leads the development of the Global Nuclear Detection Architecture (GNDA), implements its domestic portion, and leads the integration of United States Government technical nuclear forensics capabilities. The FY 2018 request funds activities to protect the United States from radiological/nuclear (R/N) terrorism by developing, acquiring, and deploying detection technologies, supporting operational law enforcement and homeland security partners, and by integrating technical nuclear forensic programs and advancing the state-of-the-art in nuclear forensics technologies. To address gaps in the GNDA and dramatically improve the performance of R/N detection and technical nuclear forensics technologies, the request also funds basic, applied, and developmental research to identify, explore, develop, and demonstrate innovative technologies."
