What thickness walls and roof are required to shield the inhabitants from the space radiation? Wouldn't it be better to be underground?

Underground is trickier, will need lots of drilling and boring. Lava tubes are annoying not flat or level. It will happen but not until the surface is established.

What is useful though is that the surface is covered in regoilth. The company that can viably turn regoilth into cement on the moon is going to make bank. Cement is a very good shield against radiation.

I've seen proposals that build in lava tubes. Some ice on the bottom, light enters from the top, you can use mirrors for additional light, and protected on all sides but 1 from radiation.
