I made a youtube video this morning that exlains this a bit.
gamma radiation comes in at different tangents. When the energy passes through dirt it is passing through atoms and molecules. It dissipates energy as it travels it also has the chance of hitting reverse feilds, or core of atoms which can deflect it. The reason why lead is effective is because it is very dense so it makes it more difficult to travel through it. The density also increases the chance of making contact with those counter fields and cores.
Its a bit like going through one line of scrimmage or one million.
another option is putting a gamma ray reflector at some stage?

for densities
Air1.2
Wood700
Water (fresh)1,000
Water (salt)1,030
Plastics1,175
Aluminium2,700
Iron7,870
Copper8,940
Lead11,340
Gold19,320
Platinum21,450
Iridium22,420
Osmium22,570
another consideration is use of gases to create lift as opposed to adding weight
These substances can sheild but sheild far to little unless you are very far underground to use them as a sheilding medium. http://en.wikipedia.org/wiki/Lighter_than_air
at smaller depths it would be mostly negligible.
air being 1.2 at sea level, you would still be better protected using methane than air.
Insulating with plastics seems to be a better solution than air for sure.. since plastics offer more protection than wood. Aluminum might be another option since it offers nearly twice as much protection than plastic and 3 times as much as wood.
the difference between plastic sheets and soil is that sheets may be able to be grounded into the surounding eart easier or even draped from the subsurface to the surface to allow for angular runnoff.
plastics offer almost no density advantage over soil
loose soil is about 1200 vs plastics 1170 while packed soil is 1600 somewhat less than aluminum. 2700 The advantage of aluminum, steel or copper layers is that they can be used to provide a structural sheet that extends into the earth wall. of course these materials may be expensive.

of course the classic is the school bus.. designed to hold oodles of weight. http://finance.groups.yahoo.com/group/cheap-shelters/message/3556
so arches grounded to the "hard points" on the bus or container should provide more support than simply mounting all the weight on the weak points.

here is a stripped bus

here is construction of an rv
eg. you might be able to use some sloped flat racks above your container to bear some of the weight
or use multiple containers stacked ontop of one another with protective materials in the upper layers, but they being stacked to the structural hardpoints on the container.
which in turn can be used for structural supports, holding tanks, supply storage etc..
example having cross sections that are burried into the earth as opposed to completely being supported by one another.
CHECK OUT the map 2:30 ON THIS ONE.. and this is only one business
dod seems to be building a lot of these underground bunkers.
every us state capital.... some holding up to 300 people not exactly dumbs but it is just this guy...
