There were sharp increases in some cancers, however from very small bases and of cancers with very low mortality, as far as I recall.

I think it's worth assuming some reduction in life expectancy for some people, but notably the estimates of lost years of life have dropped year by year, and will likely end up being negligible.

I've said it before: we could have a Chernobyl every year, and it'd still be worth it (reducing deaths) if it got us off coal sooner...

As far as I recall, there were some measurable increases in cancer incidence among children in Belarus, mostly due to milk intake

However, all that was completely drowned by a collapse of life expectancy resulting from the chaos of the 90s. We're horrified at a few tens of extra cancers, but 100M men losing 10-15 years of their life due to socio-economic circumstances doesn't raise anyone's eyebrow

Long term Chernobyl numbers[0] are highly contested.
