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 ...

Dr Kevin Fong shows how a Geiger-Muller tube can detect ionising radiation but not the type of radiation, and how detectors on the International Space Station can. Suitable for teaching physics at ...

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.
