I read that coronal mass ejections and flares are independent things that can cause solar particle events. The particles emitted by the first travels at about 1,000km/s and can reach us in days, while the particles emitted by the last travels at near light speed and can reach us in minutes. Besides that, as I noticed that the most dangerous SPEs are often associated with flares, I suppose CMEs offer smaller radiation doses in average. And according with what I read, I suppose that the X-ray emission of the flare is not a concern for someone in deep space, when compared with the SPE it can produce. I would like to confirm those things. I have found great information about equivalent doses for galactic cosmic rays and some major SPEs of the past, but info on internet is somewhat oversimplified when the matter is to tell the differences between flares, CMEs, SPEs, and the risk each one offers to someone in deep space, considering their strength and likeliness to happen. Thanks.
