What do bananas, smoke alarms, toilets and large granite buildings have in common? They're all sufficiently radioactive to set off detectors. Efforts since 9/11 to prevent the detonation of a dirty ...

Snapshots from space may someday confirm the presence of lakes and oceans on Europa–one of Jupiter’s moons–and on other planetary bodies. Imaging detectors that capture information from every ...

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 ...

The networked devices were developed as part of the SIGMA program, which began in 2014 with the goal of creating a cost-effective, continuous radiation-monitoring network that can cover a large city ...

ANN ARBOR (WWJ) --A handheld radiation camera developed by University of Michigan engineering researchers that offers nuclear plant operators a faster way to find potentially dangerous hot spots and ...

A smartphone camera can make you a walking gamma ray detector. Without needing any extra hardware, you could get a warning on your phone when you're approaching potentially harmful levels of gamma ...

Researchers at Hiroshima University (HU) in Japan have developed a way to leverage the cameras on smartphones to provide accurate radiation readings. The system they created costs less than US$70 and ...

Each day on Long Island, hundreds of police officers take to the roads to protect New York City from the unthinkable. Wearing portable radiation detectors on their belts, officers in Suffolk and ...

NEWARK, N.J. – More than 200 times each day, authorities detect radiation in containers arriving off cargo ships at Port Newark. It's in ceramic tiles, granite, pottery, kitty litter — all natural ...

Over the years we’ve featured quite a few radiatioactivity detectors, which usually include a Geiger-Muller tube, or perhaps a large-area photodiode. But in the event of radiation exposure from a ...

A lighthouse is built to shed light on rocky waters, the light turning at the top of a tower to illuminate sections of a dark shoreline that might harm incoming boats. Researchers from Los Alamos ...
