@effix Je parlais des dangers d’une eruption solaire, pas du niveau de radiation normale. The radiation risk posed by solar flares and CMEs is one of the major concerns in discussions of manned missions to Mars or to the moon. Some kind of physical or magnetic shielding would be required to protect the astronauts. Originally it was thought that astronauts would have two hours time to get into shelter, but based on the January 20, 2005 event, they may have as little as 15 minutes to do so. Une eruption violente aurait tué tous l’equipage en vol.
