Visible to the public A Hybrid Detector Network for Nuclear and Radioactive Threat Detection


Identification and tracking of nuclear materials is a problem of obvious importance, and has attracted a great deal of engineering effort in the recent past. The technical challenges of this problem are compounded by the fact that nuclear materials that are of interest vary widely in their concentrations and compositions, and are often concealed with shielding material, and buried in background radiation that is always present, but varies widely in strength and spectrum over time and space.
