I'm due to fly to Iceland from London Heathrow for two weeks tomorrow but because of a bomb threat today ALL carry on luggage has been banned from UK flights, as I understand all you are allowed is your passport and money. This means the Velvia I'm planning to take will have to go through check-in Xray machines, which I understand is not good.

Can anyone tell me if and where I can buy 120 velvia in Iceland (presumably Reykjavik)?

Is a single trip through a check in Xray machine likely to fog 100ISO velvia ? (If risking it I would certainly post the exposed film back home).

Thanks in advance for any help.
