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 ...

The Geiger-Muller (GM) tube allows a user to measure different types of radiation, including alpha, beta, x, and gamma particles. A GM tube consists of one anode and one cathode enclosed in a ...

Many portable radiation monitors include a Geiger-Mueller tube, a simple, two-terminal, gas-filled detector that generates a pulse each time a radiation event (photon or particle) impinges on the tube ...
