Making one of these detectors involves gutting a cold cathode power supply for some high voltage AC, then bumping that source up to crazy high voltage DC with a Cockcroft-Walton generator.

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 ...

Worried about radiation in the food you eat or the objects around you? Soon, you'll be able to test your environment for different levels of radiation, and other adverse conditions, with an iPhone ...

It can also convert heat to electricity, and researchers have recently exploited this thermoelectric property to create a new kind of radiation detector.

It's not essential as an iPhone, but radiation detectors are beginning to look just as good.

The detector's ability to ignore background radiation and pinpoint different primary sources of radiation could potentially make it useful to verify materials that are in storage.

It was made for spacecraft, but the radiation detector can be used in cancer patients, too.

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 ...

Is the radiation in ionization smoke detectors harmful? The U.S. Nuclear Regulatory Commission claims that if you held an ionization smoke detector close to your body eight hours a day for a year ...
