A Geiger counter, also known as the Geiger-Muller tube, is an inexpensive and useful instrument used to quickly detect and measure radiation. There are two types of radiation, non-ionizing and ...

The Geiger-Muller tube takes a small amount of charge from the power supply each time it is hit by a radiation event. Current taken from the bias supply therefore equals the frequency of events ...

How radiation can be detected Detecting radiation using a Geiger-Muller tube The ionising effect of radiation is used in the Geiger-Muller (GM) tube as a means of detecting the radiation.

Muller, Walter Description This “Zahlrohr” is a very early Geiger-Müller tube used to detect ionizing radiation. Hans Geiger (1882-1945), a German physicist, devised the basic principle in 1908.

Being in the proximity of nuclear weapons offers the chance for exposure to radiation. Thus, the Geiger Counter — or more accurately the Geiger-Muller Counter — was a significant tool.
