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.
