I'm confused what the connection is with Chernobyl.

But 2M deaths in the last 30 years is not likely correct - this interesting WHO report on the matter suggests the final toll from the radiation would be more like "up to 4k":

> The main causes of death in the Chernobyl-affected region are the same as those nationwide — cardiovascular diseases, injuries and poisonings — rather than any radiation-related illnesses
