There's some very suspicious cherry-picking going on with the author's choice of Ukrainian milk and raw numbers (which is never how public health researchers describe impact from things like this, it's per-population stats and relative increases/decreases) about childhood thyroid cancer rates. For an unspecified region, presumably Ukraine, but the author doesn't specify...also suspicious.

Chernobyl is the northern part of Ukraine. The plume was highly directional and initially blew almost directly north into Belarus:

Not surprisingly, the majority of contamination was, overwhelmingly, in Belarus:

The author goes on:

"Radiation impacts on Scandinavia and Germany, where there were major fears about the effects of the fallout, were nugatory"

Well, yeah, because very little ended up in those areas comparatively?

If you wanted to trick the average person into thinking "wow even in the country where the reactor was, there was almost no health impact", the author's repeated choices in terms of information presented would be a fantastic way to do so.

The real facts: https://pubmed.ncbi.nlm.nih.gov/16832789/

"The study carried out in Minsk showed 40-fold increase of the incidence of thyroid cancer in the years 1986-1994, in comparison to the period 1977-1985. An increase of the incidence of thyroid cancer has generally been observed in many countries after the Chernobyl accident."

Later the author goes completely off the rails with whataboutism talking about Bhopal (which he claims isn't well known. I say: it's probably one of the most famous chemical industry disasters of all time? and the China dam disaster, which is pretty well known, mostly because nuclear proponents bring it up incessantly.)

This is nearly as bad as the nuclear proponents who always compare nuclear to coal, when in the US alone solar is what's replacing nuclear at a ratio of 6MW of solar for every 1MW of nuclear, and coal has been getting phased out for well over a decade because it's expensive.
