Use a Geiger-Müller tube to measure radiation intensity and to discover how radioactive particles react with various materials.
Students gain a new understanding of how to handle radioactive sources, how to measure radiation intensity, and how radioactive particles react with various materials. Students will:
- Understand the relationship between the distance from a radioactive source and the measured activity of the source.
- Observe the penetrating ability of three common types of nuclear radiation.
- Investigate the ability of different materials to absorb energy associated with nuclear radiation.
Students gain experience conducting the following procedures:
- Using a Geiger-Müller tube to measure the activity of different radiation sources.
- Measuring the change in counts for a given time interval as a function of distance from the source
- Measur.ing the effectiveness of different types of shielding for different types of radioactive sources.
Sensors / Equipment Used:
A Geiger-Muller probe that senses alpha, beta and gamma radiation.
Radioactive sources (alpha, beta, gamma) ~ 3
Shielding materials (paper, plastic, lead)
