Reconstructing the Atomic Number of Cargo X-ray Images using Dual Energy Radiography
… U.S. deploys scanning systems at ports of entry. Radiation portal monitors are capable of identifying unshielded nuclear or radiological threats by detecting radiation that is passively being emitted from a container. Radiography systems offer complementary detection capabilities, capable of …

Simultaneous fast and slow neutron detection with superheated droplet detector and real-time readout system
… in response to needs by homeland security and radiation safety. Superheated droplet detectors (SDD) have the potential to be used in both situations because they have many distinct characteristics, such as photon insensitivity, passive operation, tissue-equivalent composition, isotropic …
