I would like to know if the current and historical radiation exposure rates
on board the International Space Station are on the web somewhere. I
believe that exposures to personnel are 0.1 to 0.2 Sv per 6 months
routinely, but am curious about the exposure rates during the recent
coronal mass ejection (CME) that produced northern lights visible in the
southern US (a rare occurrence). I was told by a solar expert (Jan
Alvestad) that "The increased radiation levels were not because of the CME,
rather a minor M class proton flare at the northwest limb of the Sun. This
event occurred several hours after the event which produced the CME".
Any link to more information would be appreciated.
