Maura's two posts below have me wondering what would happen if Dublin had to be evacuated. I remember after September 11 there was a lot of near panic about the possibility of a terrorist attack on Sellafield. The government's response to this panic was to send iodine tablets to every adult in the state.
I really doubt there's any plan to evacuate Dublin nor can I imagine any event that might warrant an evacuation. I suppose if the south coast of England and Wales were once hit by a Tsunami, it's possible here too.
