Well, look at it this way: what happened at Fukushima was an ageing, poorly maintained reactor built on a fault line in the Pacific Ring of Fire got hit by a record-setting earthquake AND a tsunami... and despite all of that the damage is not that massive. I mean, yes, the situation is a big mess and I wouldn't want to be in charge of handling the clean up and everything, but let's be fair: considering all of the circumstances it's impressive the damage wasn't way worse.
So there were and will be no negative health effects from the radiation, whereas 100% of the deaths and other negative effects on people were due to Radiophobia.
one of their problems was they didn't know what rad levels are to decide how to perform evacuation, because most sensors were shut down bc of tsunami. They were acting blind with no data and were assuming the worst
