Greg Poe, a student at Travis High School in Richmond, Texas, brought the Berkeley Detector onto a trainer-airplane. His goal was to measure the muon flux at different altitudes. In order to do this, he took measurements at ground level (about 3 msl), 4300 msl, and 8500 msl. After statistically comparing his data, he found that muon counts rose with the altitude. "It looks like it's rising exponentially, but this would be more concrete with more data at different altitudes," he says, "Luckily, I'm donating the detector to my high school so someone else can find out." Greg brought his data to the Houston Science and Engineering Fair and received an honorable mention in the physics category.
