They knew radiation caused the charge on an electroscope to dissipate quicker. They suspected the main source of background radiation was the Earth. To show evidence for this they took a charged electroscope up in a balloon. It should have discharged less quickly. It discharged even faster, showing that radiation was coming from space. Makes you have a lot more respect for electroscopes knowing this.Dan Burnshttps://www.blogger.com/profile/02319981523410756611noreply@blogger.com
