Secret Tube Trains under London?

26 Feb 2007, Graeme Wall remarked: A dirty bomb is a conventional explosive device designed to spread radioactive 'shrapnel' around, any biological component would be killed by the radioactivity long before delivery. Not quite. It's a conventional explosive device designed to spread *biological* 'shrapnel' around. It doesn't have to be a very big bang, either. Just enough to do the spreading. And nothing radioactive involved at all. -- Roland Perry |

And nothing radioactive involved at all. I beg to differ; my understanding is that a 'dirty bomb' has always been thought of as being radiological in nature. A chemical or biological weapon doesn't *need* explosive - the agent can simply be released into the environment and allowed to disperse naturally. Irradiated material is most effective when dispersed as widely as possible, and isn't affected by heat (which can of course destroy biological, and to some extent possibly chemical agents), hence the 'bomb' makes sense.

Whatever term people are familiar with, that latter weapon was the risk I was meaning. -- Roland Perry |
