Teatcher's guide and student activities.

The Radioactivity Lab examines the intensity of radiation over distance, demonstrating the effects of the inverse square law. Students investigate the intensity of radiation being emitted from a radioactive Strontium-90 source, by setting distances at which a Geiger counter measures radiation, and collecting radioactive particle counts at each of these distances. A table holding the radioactive source is rotated until the source is aligned with a hole in a thick lead plate.
