PNNL’s Signature Science and Technology Division works across fundamental science, research and development, and operations to counter emerging national security threats. We combine new capabilities with measurement, analysis and data analytics for a growing threat landscape. By moving signature detection toward mission relevant speed, we deliver the solutions necessary for complex mission needs, from explosives detection and biological threat detection to special nuclear materials.

PURE MATERIALS Produce radiopure, chemically pure, and structurally pure materials for sample collection, sensing, and next-generation computing.

THREAT AGNOSTIC DEFENSE Countering biological and chemical threats in a world without meaningful norms.

SIGNATURE EXPLOITATION FOR NUCLEAR MONITORING Make measurements at the speed and scale of mission relevance though analysis of cross-domain data.
