Something I like to tell people who ask about nuclear meltdowns after an apocalypse or civilizational shutdown, is that as long as you don't drink the milk for a few weeks your real concern will be the eventual failure of hydro dams
Obviously, any release of radio iodine large enough to cause public health concerns is also very likely to release large amounts of radio cesium and such.
Filtered vents on the containments are the way to go. Silver plated zeolite can easily remove 99% or Cs and I, and adding a metal fiber filter can push it to over 99.99%. At that point there is no requirement for offsite actions.
There's a confounding factor when attempting to compare Fukushima with Chernobyl. A significant fraction of the Ukraine and Belarus population was iodine-deficient, which both increases I-131 uptake and is itself an independent thyroid cancer risk factor, whereas the normal Japanese diet is rich in iodine.
I;m not sure I'd call this a confounding factor, maybe a multiplying factor. Yes, some of the Chernobyl kids were deficient in iodine and that made things worse. but the key difference is these kids got some very impressive dose rate profiles and the Japanese kids did not.
Yes. Fukushima vents are manual. I am about as big a fan of manual venting as I am of manual airbags in a car, with presidential override. Saturday morning cartoon level silly. Vent should be passive. Simple loop seal.
Still buffer zone is smart. Another reason to go offshore. No cows either

I think you still have to allow for the fact that the filters can be by-passed, a la Fukushima.
A precision bunker buster will do nicely. I still want my buffer zones.
