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 ...

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 ...

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 ...

Members of the bomb squad from the Franklin County sheriff's office hope their new radiation detectors, small enough to hook onto a belt, never have anything dangerous to detect. "This is one of those ...

Gamification A new design inspired by Tetris could reduce the cost and boost the accuracy of accurate radiation detectors used for monitoring nuclear sites. (Courtesy: Ella Maru Studio) Inspired by ...

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 ...

After the March 2011 meltdowns at the Fukushima Daiichi Nuclear Power Station in Japan, which breached reactor containment systems and resulted in the evacuation of about 150,000 people living within ...

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 ...

The Universe contains much better particle accelerators than anything we humans can contrive. While the Large Hadron Collider (LHC) is capable of sending individual protons to energies of 7 trillion ...
