Re: under ground bunkers
spm,
Here's a good place to start:
www.ki4u.com
The guy that runs this site has compiled tons of info about radiation shielding, shelters, etc. and also sells nuclear war/accident survival stuff like Potassium Iodide, radiation meters, etc. He's extremely legit and very well-known in his field - i.e., When the gov't needs KI, they usually call him first.
His name is Shane Connor and he's a good guy to deal with. If you decide to contact him tell him Brutus from TimeBomb 2000 sent you.

I have much the same ideas as you on building a shelter from a shipping container. To put it underground it needs heavy duty waterproofing and shoring on the inside to support the weight of the covering dirt. My idea is tar mastic and French drains for the outside and timber for the inside - like 4x4 posts and 4x6 headers about every 2-4 feet of the length of the container.
Large diameter culverts in relatively long lengths have gotten enormously expensive over the last ten years or so. Old shipping containers are pretty cheap and for the price difference up front, you could afford to cash flow a lot of improvements to a container to make it suitable.
