The purpose of our research was to determine if sheet metal of widths ranging from 1/16th of an inch to ¼ of an inch (in 1/16th of an inch increments) would have a shielding effect in the detection of muon flux. The experiment was performed by using two pair of scintillator paddles with steel plating in between. We found that a quarter inch of steel was effective in reducing the control flux of 479 events/minute/meters2 to 466 events/minute/meters2. Reducing the shielding yielded diminishing returns, to the point where 1/8th of an inch plating gave statistically insignificant results. These results suggest that steel is capable of being used as a shield from cosmic ray. This research could be continued by testing a larger variety of steel plating thicknesses, and even testing different metal’s effectiveness in cosmic ray shielding.
