Detecting and measuring ionizing radiation
In the beginning of radium research work, the photographic plate was used to study the new phenomena. However, ease of handling, relatively low cost and high sensitivity soon made the gold-leaf electroscope the preferred measuring instrument for work with radio-active material. Various types of electroscopes were

gold-leaf electroscope
A gold-leaf electroscope is an instrument used (mainly historically) for the measurement of electric charge or potential, based on one or two fine gold foils suspended vertically and free to deflect under electrostatic repulsion when an electric charge was applied (Figure 1). Although never very accurate, the instruments could sometimes detect as little as 10 –14 coulomb and were used to ...

The photoelectric effect can be observed on a gold leaf electroscope; A plate of metal, usually zinc, is attached to a gold leaf, which initially has a negative charge, causing it to be repelled by a central negatively charged rod . This causes negative charge, or electrons, to build up on the zinc plate

Introduction to Electroscopes The Invention of Electroscopes. It is probably fair to say that the electroscope was invented in 1746 by the Frenchman Jean Nollet, but that the gold leaf electroscope (which is what we generally think of when we think of electroscopes) was invented by the Englishman, Abraham Bennet (Phil.

How does the gold leaf electroscope work? Metal plates, metal rods, and the two gold leaves are conductive materials. Therefore, electrons can freely move through them. A gold leaf electroscope should be neutralized before using it. The electroscope is grounded to neutralize. This can be done by simply touching the metal plate of the electroscope.
