FYI, there were zero radiation deaths from Fukishima, although there were ~2200 from the evacuation. Keep in mind this was during the aftermath of a tsunami.
I think there was a lot of hard work that went into to prevention of anything worse happening at Fukushima. At least that is what I remember from reading the iaea report a couple of years ago. I remember it being a very good and interesting read: https://www-pub.iaea.org/MTCD/Publications/PDF/Pub1710-Repor...
