Novel Radiation Surveillance Technology Could Help Thwart Nuclear Terrorism
2012-05-01 12:32:42

Homeland security Among terrorism scenarios that raise the most concern are attacks involving nuclear devices or materials. For that reason, technology that can effectively detect smuggled radioactive materials is considered vital to U.S. security. To support the nation's nuclear-surveillance capabilities, researchers at the Georgia Tech Research Institute (GTRI) are developing ways to enhance the radiation-detection devices used at ports, border crossings, airports and elsewhere. The...

By combining three layers of detection into one new device, a team of researchers from Japan has proposed a new way to monitor radiation levels at power plant accident sites. The device would be more economical that using different devices to measure different types of radiation, and could limit the exposure times of clean-up workers by taking three measurements simultaneously. Radioactive decay produces three flavors of emissions: alpha, beta, and gamma. Alpha particles comprise 2...

By swapping one superconducting material for another, researchers at the National Institute of Standards and Technology (NIST) have found a practical way to boost the efficiency of the world's fastest single-photon detector, while also extending light sensitivity to longer wavelengths. The new tungsten-silicon alloy could make the ultrafast detectors more practical for use in quantum communications and computing systems, experiments testing the nature of reality, and emerging applications...

The bolometer, invented in 1878 by Samuel Pierpont Langley, measures the energy of incident electromagnetic radiation. It consists of an absorptive element connected to a heat sink through a thermal link. The absortive element raises its temperature above that of the heat sink when radiation impinges on it. The higher the energy the higher the temperature rises. Old bolometers used metals while newer ones used semiconductors and superconductors as the absorptive elements. Bolometers can...

A metal detector is a device that finds metal that may not be visible. The basic metal detector is composed of an oscillator producing an alternating current that passes through the coil producing an alternating magnetic field. If electrically conductive metal is close to the coil then the magnetic field is disrupted and thus the metal detector can sense the hidden metal. The first metal detectors were developed in the 1960s and were used for mining and other industries. They were used...
