Astronaut Radiation Exposure
Astronaut Radiation Exposure refers to the amount of ionizing radiation that an astronaut is exposed to during spaceflight. The sources of radiation include galactic cosmic radiation, solar particle events, and trapped radiation in the Earth's magnetic field. The effects of radiation exposure can range from acute radiation sickness to long-term health risks such as cancer and cardiovascular disease. Astronauts are exposed to higher levels of radiation than the general population on Earth due to the lack of protection from the Earth's atmosphere and magnetic field. NASA and other space agencies have established radiation exposure limits for astronauts and developed shielding and monitoring technologies to minimize the risks. However, the risks of radiation exposure remain a significant challenge for long-duration spaceflight missions such as a manned mission to Mars.
