[None, Passengers and crew in high-flying aircraft at high latitudes may be exposed to elevated radiation risk, Radiation hazard avoidance recommended for astronauts on EVA; passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk, Unavoidable radiation hazard to astronauts on EVA; passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk, Unavoidable high radiation hazard to astronauts on EVA (extra-vehicular activity); passengers and crew in high-flying aircraft at high latitudes may be exposed to radiation risk]

["None", "Infrequent single-event upsets possible", "Single-event upsets, noise in imaging systems, and slight reduction of efficiency in solar panel are likely", "May experience memory device problems and noise on imaging systems; star-tracker problems may cause orientation problems, and solar panel efficiency can be degraded", "Satellites may be rendered useless, memory impacts can cause loss of control, may cause serious noise in image data, star-trackers may be unable to locate sources; permanent damage to solar panels possible"]

["Minor impacts on HF radio in the polar regions", "Small effects on HF propagation through the polar regions and navigation at polar cap locations possibly affected", "Degraded HF radio propagation through the polar regions and navigation position errors likely", "Blackout of HF radio communications through the polar regions and increased navigation errors over several days are likely", "Complete blackout of HF (high frequency) communications possible through the polar regions, and position errors make navigation operations extremely difficult"]
