The number of disintegrations cannot be determined easily in practical work, but the count of radioactive particles detected by a Geiger Muller counter is a useful approximation at this level ...

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 ...

[Ryan Harrington] shows us how to make a Geiger counter with very few parts, and you can see the results in the video below. The glut of surplus Russian tubes has made this a common project ...

Description: A geiger counter and a selection of radioactive sources. Available sources are: Thallium 204 (beta); Strontium 90 (beta); Cobalt 60 (gamma); Coleman propane lamp mantle containing ...

The Geiger counter remains a popular build, and could be a handy tool to have in a time of rising tensions between nuclear powers. [Leonora Tindall] had tinkered with basic units, but wanted a ...

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 ...

Kit includes all components needed to build a working Geiger counter, including a high quality printed circuit board, sensitive Geiger-Muller tube, laser-cut acrylic case, and 2xAAA batteries.

that the efficiency of the Geiger-Müller counter increases at first as the voltage is increased and finally approaches unity.
