We have two other sources of radiation. Cosmic rays and solar energetic particles. These are mostly high speed protons and helium. They do direct damage and can produce secondary radiation.
They're best shielded by light materials. Hydrogen is good.
Oh. On this trip, every now and then, you're going to see a bright flash of light. That's a cosmic ray interacting with your eye or a visual neuron.
Light flashes. Got it. An unfriendly reminder from the universe that it's messing with my brain.
