Cosmic rays and solar energetic particles. These are mostly high speed protons and helium. They do direct damage and can produce secondary radiation. ~ @8,336,163,65 #fefffc ~ @69,334,166,24 #fefffc ~ @2,334,167,94 [flo]They're best shielded by light materials. Hydrogen is good. ~ @5,549,220,128 #fefffc ~ @23,539,239,93 #fefffc ~ @0,548,218,141 [flo]Oh. On this trip, every now and then, you're going to see a bright flash of light.
