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 ...

On the outside, a Geiger counter seems like a complicated thing. And you might think a device that detects a dangerous, mostly invisible threat like radiation should be complicated. But they’re ...

Three parallel Geiger-Muller Tubes were used in this project in order to produce a Cosmic Ray Muon Detector that is easy to build, low cost, and contains usable output to graph, visualize, or sonify.
