The Gold Leaf Electroscope Dry air is normally a good insulator so a charged electroscope will stay that way as the charge cannot escape When an electroscope is charged the gold leaf sticks out because the charges on the gold repel the charges on the metal stalk When a radioactive source comes near the air is ionised and starts to conduct electricity This means that the charge can
