That problem turns out to be far more difficult than it sounds.  An atmosphere is a great way to filter some kinds of particularly harmful radiation.  A sheet of metal creates a bunch of secondary particles when struck by high-energy particles.  To filter out the bad stuff requires a lot of material.  This makes me think we must have a way to use material already out there, such as from the asteroid belt.
