I remember back in 80s when I was a kid and this happened to see trucks backed up in the inner-German border because they and their cargo was to radioactive to be allowed to pass westwards.
They told us not to eat anything from our own gardens that season.
Farmers were demanding money from the government about missed harvests and all sorts of other things like that.
I have no idea how much of that was overreaction, but there was at lest enough radioactivity reaching western Europe to prompt those overreaction.
