Cosmic Radiation.Cosmic radiation refers to sources of radiation in the form of cosmic rays that come from the sun or from outer space. At ground level the muons, with energies mostly between 1 and 20 GeV, contribute about 75 % of the absorbed dose rate in free air.The remainder comes from electrons produced by the muons or present in the electromagnetic cascade.
