Secondary radiation in space

Web25 Aug 2024 · The two main types of hazardous radiation in space are solar energetic particles and galactic cosmic rays; the intensity of each depends on solar activity. Galactic cosmic ray activity is lowest within the six to 12 months after the peak of solar activity, while solar energetic particles’ intensity is greatest during solar maximum, Shprits said. WebManned missions beyond LEO will face the challenge of radiation from three different sources: solar particle events (SPE), galactic cosmic radiation (GCR) and intra-vehicular …
