And you know perfectly well that the Greenpeace estimates are bullshit and just as biased as DuPont estimates of deaths from PFOA. Also there's no such thing as "long term death-rate", you can only estimate possible years of life lost as result of early thyroid cancer because this is what the iodine isotope released in Chernobyl can impact. The best estimate was ~200 cases of thyroid cancer over 20 years. This is how many people died in UK on wind tower accidents.
