I've been reading lately that it takes three feet of dirt to stop gamma radiation. Makes me wish I had bought a house with a basement. I've been reading about Russia lately. In 05 or so they ran a simulated nuclear attack on the US. I'm sure we do the same in return but us doing it comforts me... Them doing it worries me. I'm not interested in hearing any bravado or any "I want a beer and a lawn chair to watch the fireworks" comments please. I'm interested in any knowledge experienced or well read people have. Thank you.
