So, in spite of the “SPF 20,000,000,000,000” comment above, any radiation that come with an ejection like that gets filtered out by the atmosphere? That PDF says that an EMP doesn’t have a direct effect on people, but the article described this as “a curtain of solar material” so I thought there might be other things in it than just an EMP.
Thats my take from the PDF too.
I suspect that at this stage no one really knows what the exact effects of a CME or EMP would be. There are so many variables and such a small amount of empirical data that most of what we read seems to be theoretical.
I have been digging around to see if there is any data pertaining to EMP type effects from the Nagasaki and Hiroshima bombs but haven't found anything yet. The focus is naturally on the tremendous magnitude of the physical effects of the detonation and subsequent radiation.
