Mostly, yes, but also consider that both were exceptional circumstances that happened to outdated reactors.

IIRC Fukushima didn't actually leak enough radiation out to cause any significant environmental harm - quite possibly, most of the evacuations weren't even necessary, and the total toll among responders was only 25, with only 1 death.

Chernobyl was much worse, but other than responders and the high incidence rates of thyroid cancer in young children close to the disaster area, the total casualties were also lower than people assume. A lot of the early estimates were massively inflated.

Honestly it's quite possible that in both cases, we could have done much less relocation and evacuation, especially the fukushima response was largely driven by Japan's fear of nuclear technology.
