In 1983 there was a huge panic in UK caused by a increased rate of #leukemia among children living near on particular nuclear site (Sescale). Media were fast to jump to conclusion, ignoring science which couldn't explain the cause back then, but pointed out similar clusters elsewhere far from any nuclear installations and insisted nuclear is unrelated.

Today we know it was particular infection that caused it and #nuclear was indeed unrelated.
