First Use of Muons

The recording of the first practical application of the muons occurred almost twenty years later in 1955 when Eric George consistently measured mule flow attenuation measurements to measure the thickness of the ice over tunnels excavated at a mine in Australia. At the time, the equipment that George used, consisted of a telescope with a Geiger counter that mediates the ionization provoked by the muons. By measuring the attenuation of the flow, it is possible to extract information about the crossed material and its interior, somewhat similar to how an X-ray is obtained.
