Charged particle radiation that enters the heliosphere continuously from outer space from all directions. The radiation contains electrons (approximately 2%) and a broad range of charged particles from protons up to high Z particles with energies up to several hundreds of GeV and even higher. The fluence rate of GCR in the heliosphere is inversely correlated with the solar activity. It is caused by the solar magnetic field, which is coupled to the solar wind. (ICRP Publication 123, 2013)
