Understanding Radioactivity and Radiation Measurement Techniques in Nuclear Energy

Explore the fundamentals of radioactivity and how scientists measure radiation using instruments like the Geiger counter. This resource provides insights into what Geiger counters measure, the significance of clicking sounds, and concepts such as "Counts per minute" and "microSieverts per hour." Students will learn to create a model of radiation levels based on real data from the Fukushima incident, enhancing their understanding of radiation risk and safety measures, particularly in evacuation scenarios.

  3. What are the scientists measuring? What instrument is used in this picture?

  4. Investigation • What does a Geiger counter measure? • What does it mean if the Geiger counter is making more clicking sounds? • What is meant by “Counts per minute” or “Counts per second”? • What is a microSievert per hour?

  5. Evacuation Zone with Geiger Counter

  6. iLab Reactivity Learning Objectives • Students will create a model of the radiation levels based on data from the Fukushima video, and use this type of model to predict the radiation levels at 1 km from the power plant. • The purpose of the iLab is to gather data to allow a model to be created.
