Why are astronauts at greater risk from solar radiation than people on Earth?
Answer
They operate outside the full protection of the atmosphere
Human populations on the ground are protected by the deep atmospheric well and the Earth's magnetic field, which absorb the most dangerous components of solar radiation. Astronauts aboard the International Space Station are positioned outside this protective shielding. Consequently, they are exposed to higher levels of radiation and require rigorous mission protocols and shielding to mitigate potential health risks.
