Lunar Habitats

When our intrepid explorers finally reach the Moon again and set up an encampment, where will they live? NASA has plans to build inflatable structures to house our first lunar colonists (Space.com - NASA Tests Inflatable Lunar Shelters): 

The inflatable structure is made of multilayer fabric and looks like an ungainly white robot with legs. The main unit is 12 feet in diameter and 18 feet tall. It has a volume of about 1,600 cubic feet and is connected to an airlock, also inflatable. The two spaces are essentially pressurized cylinders, connected by an airtight door.

I wonder how well that kind of structure will do in shielding them from solar radiation? That is one of the great dangers the colonists will face.
