Knowing the Fallout

The Union of Concerned Scientist have created a flash animation explaining the likely results of a 'mini-nuke' bunker-buster type strike against Iran.

Essentially, the bomb the US currently has (or at least the one they're telling us about) won't work against Iran fortified bunkers and the resulting fallout will contaminate countries as far away as India. The city of Esfahan, only a few miles from Iran's nuclear facilities will be at highest risk.
