Beta radiation can be used to measure the thickness of aluminum foil during production and to automatically control the speed and pressure of the rollers that press the metal into foil. This is shown in the diagram. The Geiger counter measures the amount of radiation that comes through the foil from the beta source on the other side. The Geiger counter is connected to a system that controls the rollers.
