“Passengers seated next to an airplane window receive higher radiation exposure during a flight than passengers seated in aisle seats.”

Available evidence does not establish that window seats receive a higher overall radiation dose than aisle seats. Aircraft-shielding models suggest aisle corridors may sometimes have less protection from cosmic radiation, while increased exposure near windows mainly concerns daylight UVA, a separate non-ionizing form of radiation. The claim therefore overgeneralizes across different radiation types and aircraft configurations.

“Cosmic radiation exposure on a commercial flight increases as the aircraft flies closer to Earth's magnetic poles.”

Commercial-flight radiation exposure generally rises toward Earth’s magnetic poles because geomagnetic shielding becomes weaker at higher magnetic latitudes. Multiple authoritative and peer-reviewed sources support this relationship. At the highest latitudes, exposure may plateau rather than continue increasing without limit.
