When you think of a radiation detector, you’re probably thinking of a Geiger tube and its high voltage circuitry. That isn’t the only way to measure gamma radiation, though, and [Alan] has a ...

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 ...

Both ionizing and non-ionizing radiation can be harmful to both organisms and the natural environment. Radiation testers either measure the levels of Ionizing or non-ionizing radiation from Nuclear ...

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 ...
