Not even cosmic radiation can make it to the surface.
Only secondary particles created in the upper atmosphere.
X-ray cannot penetrate the atmosphere.
Even relativistic velocity protons or electrons wouldn't have a chance. Yeah, they're 'fast' but they have no real mass or momentum. And they've got to navigate the magnetosphere, which typically eats any charged particle which comes it's way.
The solar wind is less than 1-millionth as strong as lower atmospheric winds.
If you spent an average lifespan orbiting Earth in a spacesuit, and holding out a coffee cup, normal to the solar wind, all that time, in 79-years, you wouldn't collect enough 'wind' to fill it.
During a solar flare, and holding out your arm into the 'blast', you wouldn't feel a thing.
