• In 1912, Victor Hess In 1912, Victor Hess took a radiation took a radiation counter (using a counter (using a gold leaf gold leaf electroscope) on a electroscope) on a balloon flight.balloon flight.

• Traveling 17,500 Traveling 17,500 feet without oxygen, feet without oxygen, he observed the he observed the radiation increase in radiation increase in his balloon climbed.his balloon climbed.

By the time Cosmic Ray Man reaches the Earth’s surface, there are By the time Cosmic Ray Man reaches the Earth’s surface, there are mostly muon’s and electron’s left…about 5/6 and about 1/6 mostly muon’s and electron’s left…about 5/6 and about 1/6 (respectively). So the higher the primary energy, the more muons and (respectively). So the higher the primary energy, the more muons and electrons are on the ground.electrons are on the ground.
