You argue it is safe. When it is not (Chernobyl, Fukushima) then you argue it kills less people. That is before considering the possibility of these sites being attacked during war (see Zaporizhia in Ukraine) and how centralized they are vs solar.

Belarus had markedly increased general cancer rate post-1986. At the time most of that was fatal. None of that naturally is included in site personnel and firefighter fatalities that IAEA recognises as the only casualties.

When I was a student I met a Chernobyl liquidator in his 30s on a local train. He said he was dying of leukaemia and looked like it. As a thought experiment, how would you argue to him that his death is unrelated?

Western part of USSR had also an explosion of thyroid cancers and tumors among children. Fortunately it was very treatabe. Because it was screened as a known consequence of the fallout my brother in law had an intervention early.
