You keep quoting that sentence, but it doesn't even imply, much less outright say, that the evacuation was "almost certainly overreaction". Both well justified and poorly justified evacuations come with mental health impacts. If our house burns down while we're in it and we get out in time, the mental health impact would be the largest health concert; that doesn't mean we should stay in it. You can argue that the Chernobyl evacuation was an overreaction, but not using that paragraph or the enclosing section in that report. Yet you persist in doing so.
