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.

As future missions look to travel back to the moon or even to Mars, new research cautions that the exposure to radiation is much higher than previously thought and could have serious implications on both astronauts and satellite technology.
