The glass domes would be for growing crops.

Most habitation would be underground (hence the mining drones) to reduce radiation exposure.

Overall radiation exposure would be higher, and life expectancy would take a hit, accordingly. This is a trade-off, not a non-starter. I too would like to see a bit more discussion of specifics, but I also don't see this as the Achilles' heel that many would make it.
