Well, at least for Germany it was the actual nuclear fallout over large areas of the country after Chernobyl. Which is btw still measurable today. [1] That's a pretty scary thing to happen to you and one just has to accept that these are the actual lived experiences of people that form their opinions.
Radiation detectors can detect very low levels of radiation (far below any measurable health effects, for instance), so claiming we can still detect fallout from Chernobyl doesn't really say anything.
