Ground Albedo Neutron Impacts to Seasonal Variations of Cosmic-Ray-Induced Neutron in Medium Geomagnetic Latitude and Antarctica: Impacts on Soft Error Rate
International audience This paper investigates the impact of ground albedo neutrons in the terrestrial radiation field and their seasonal variations. A modeling methodology is proposed, it is based on ATMORAD (atmospheric shower modeling) and GEANT4 simulations taking into account the soil character...
