I read an article recently explaining that the american military have been trying to make dirty bombs for a long time, and have found them to be useless, as you have to be exposed to the radioactive material for a very long time for it to damage you, and normally any dust just blows away and disperses to safe levels. I forgot where it was, but the article claimed the dirty bomb scare is just another part of the "keep the public afraid" tactics being used by governments in Britain and america. I dont know if this article was legit or not, anyone?
