New technology could improve radiation risk warnings for future deep-space astronauts

New technology that detects radiation from the Sun in real time and immediately predicts subsequent health risks could protect astronauts on future deep-space missions, according to a new study. Astronauts face dangers during solar energetic particle, or SEP, events, which occur when an eruption in the Sun’s atmosphere hurls high-energy protons out into space. These protons can penetrate the walls of a spacecraft and enter the human body. This radiation can cause immediate effects such as nausea, performance degradation and other acute radiation syndromes, while long-term effects can include cancer, degenerative tissue damage, heart disease and damage to the central nervous system.
