A multi-institutional team of physicists and engineers has developed a laser-based radiation detection system that operates from as far away as 10 meters and perhaps farther. Their research is ...

Maintaining international nuclear security requires tracking and monitoring fissile materials, such as plutonium and uranium. Standoff radiation detectors, which can measure radioactivity from afar, ...

Radiation monitoring has long depended on bulky, specialized instruments that are scarce outside hospitals, research labs, and nuclear facilities. Now a wave of research is turning the cameras and ...

Security concerns over radioactive materials have persisted for many years. Airports and other public locations now routinely employ radiation detectors, and nuclear regulators need to be able to ...
