That's interesting. I didn't know that cosmic rays were directly
responsible for putting some radioactivity in our foods. I thought
it all came from the ground.

So if we stick with the 2 meters of shielding (441 g/cm^2) we should
have a cosmic ray reading of 250 millirems, compared to 52 for
Denver and 26 for Miami. Absent 250 millrems from radon and other
Earth sources, we're better than par. But if the cosmic rays are
indeed interacting with the Nitrogen in the atmosphere, we'll have
5x the cosmic ray sources, and probably 5x the C-14. Can this be
mitigated in some way?

If we grow our food in pods with less radiation shielding, the
radiation itself won't harm the plant, but will the radiation work
its way into the atomic structure of the food, and then into our
bodies? Anyone have information on this?
