Determining the Relationship Between Distance and Radiation Count

Students measure the radiation count rate as a function of distance. They use their measurements to make predictions about the count rate at other distances. By inspecting the data, they find out the count rate varies by the inverse square of the distance. They develop a mathematical model that predicts count rate and explore its limitations.
