WebElectronic devices suffer long-term radiation effects, mostly due to electrons and protons. The main sources of these particles are Solar Energetic Particle Events - which usually occur in association with solar flares - and the South Atlantic Anomaly (SAA) - where the Earth's magnetosphere dips closest to the earth, causing more trapped radiation.
