Thirty years ago, I was studying French at Guildford and some of my fellow students were evacuated from Ukraine, having their clothes confiscated and undergoing decontamination en route. Of course, as they had been in Kiev, they weren't really in any imminent danger, but it was quite dramatic. A group of us then flew to Montreal for a 3-month course, where the local launderette manager (a Ukrainian) wouldn't let us (or anyone else from Europe) into his establishment for fear of radiation.
It did dominate many aspects of the news for quite some time.
