The objective of the lesson is for students to learn about the relationship between distance and intensity of radiation, and also to consider the many sources of radiation in our environment and their effect on our health. Also, students will practice clearly communicating scientific results in the form of a lab report.
Students will perform some background research, and then remotely operate the equipment at the radiation lab at the University of Queensland in Australia to test their hypothesis. All of this is available for free for all high school students. Its a great resource!
