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 ...

In lieu of spending a fair bit of money on dedicated muon detectors, you can also hack such a device together with two Geiger-Müller tubes and related circuitry for about $100 or whatever you can ...

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 ...

In this lesson, students will investigate the nature of radioactivity and the effect of both distance and shielding materials on different radioactive sources using a Geiger-Muller tube with a counter ...

UK astronaut Tim Peake monitors his radiation exposure using a TimePix detector. Using a student from the audience to help, Kevin shows that a Geiger-Muller tube can be used to detect ionising ...
