Radiation from Deep Space

 Despite what is squabbled about in cycles world-wide, the Earth on which most of live is not the "be all & end all" of environmental sources.
 The sun (Sol), has it's storms as well.
 These storm can, and do effect what happens here on Earth. These effects probably won't be felt so much by most people, but if you are a frequent air traveller, you may have some cause for concern. A nice little peice from livescience.com makes some sense , of what, could sound complicated. Have a look at http://www.livescience.com/16273-solar-storms-space-radiation-risk-astronauts.html .

It gives a good factual look, without the BS politic's.
