I think it was in fact quite a lot less globally than Chernobyl was

By a couple of years after Chernobyl, any I-131 it released would all have
decayed. Every single atom.

Oh yes. I know that. That's why apart from a week after a reactor pops
its significant, the stuff people are more worried about is strontium 90
and caesium 137 (half lives 29 and 30 years) because they are active
enough to be of possible concern and yet long lived enough to be around
for a decade or more and both are biologically active.

both are beta decay
I think both end up in bones and teeth. Hence there were scare stories
about leukemia...

Calcium analogues.

Exactly so
