> Not at a dangerous level, say more than eating a banana.
Born 1986 in Germany and I got a rare metabolism illness that only ~2000 more people have, all born around June/July/August in 1986 in Western and Middle Europe with some exceptions distributed around as late as born in September and October. But the Spring of 1986 was probably just a famous year for pregnant women eating exceptionally many bananas I guess?
At least I agree that dams killed more people than that specific event. But wait till you see the numbers for fossil fuels ...
Fossil fuels, and especially coal, have worse impact in total but they are typically more diffuse. So I left them out of the discussion.
Are people able to move back into the Chernobyl fallout zone in the next few thousand years? No.
The dam breaks killed and hurt magnitudes more people.
