Sigh - but can we trust FEMA?

This article contains a link to a planning guide for surviving a terrorist nuclear bomb, and the gist of it all is to shelter in place for as many hours as you can if you survive the blast. Even sitting in a car for several hours reduces your risk of death from fallout by about half. Being in a basement or underground garage is even better - remember fallout shelters?

The planning guide mentions EMP, too - it's unlikely to have effects outside the blast damage zone with bombs the size terrorists are most likely to use - 10 kilotons and less. Even if your stuff survives the blast but is fried by EMP, gear brought into the area will still work; if there are working cells, for example, outside cellphones will still make calls.

The advice is to be able to shelter in place for 72 hours until FEMA comes to your rescue. Without regard to snarkiness about FEMA, the guide is ~130 in .pdf format. I've scanned through it but not read it yet, and it seems to be to be helpful in combatting the hysteria that will arise if a terrorist nuke goes off - preparation goes a long way toward survival.
