Abstract
The distance dependence of beta decay, a type of ionizing radiation, is measured using a Geiger counter. The decline in radiation magnitude as distance increases is measured to be a 1/r^2 relationship. During the experiment, a plastic sheet is used to determine the extent to which plastic shielding affects radiation magnitude. The experiment concludes that the plastic shielding has a large effect on the measured magnitude, but would not be an ideal material for shielding.
