In this experiment you will explore the penetrating power of different types of radiation. A Geiger counter is used to measure the radiation coming from four different radioactive sources, which can be selected by rotating a turntable. A second turntable can be used to place four different types of absorbers between the radioactive source and the detector.

The further you are away from a radioactive source, the better! This experiment will demonstrate how the amount of radiation decreases with increasing distance from the source. A Geiger counter is used to measure the radiation coming from a real radiation source at a distance selected by you.
