Discharging an electroscope through ionization. Both negative and positive ions are created by the candle in roughly equal amounts. The static master holds a Po210 sample, which is an alpha emitter, and leaves a trail of positive ions and free electrons. Both ion sources will discharge positively and negatively charged electroscopes. caution Radiation from polonium is dangerous if the solid material is ingested or inhaled.
