The Effectiveness of Various Materials for Radioactive Shielding

We performed an experiment that tested the ability of certain materials (wood, aluminum, polyethylene, lead, water, concrete, and clay) to block alpha, beta, and gamma radiation. Our hypothesis stated that lead would absorb the greatest percentage of emissions from all three radioactive sample types. Using a Geiger counter interfaced to a computer to quantify the effectiveness of these shielding materials, we collected data that validated this hypothesis.
