Obviously you don't understand what a logical fallacy is, the quote at the beginning of my post is wrt the explanation of the post hoc ergo proctor hoc fallacy, in that the timing of events does not necessarily mean that one thing led to the other.
My following statements demonstrate how this logical fallacy is generally used to further arguments without any causal link.
In fact my reasoning is such that whatever caused chernobyl is irrelevant and the effects of the event may be felt today, however without demonstrating a direct causal link it is scare mongering to point out that there is a link.
Much in the same way as surveying 12 autistic childrens parents to see whether or not they had the MMR vaccine, then declaring because of 12 autistic kids who had it, MMR causes autism. In that example they didn't even use a control set, and didn't look at the overwhelming statistics to the contrary.
And for the record, the fall out cloud from chernobyl followed south, then west, then north IIRC. Missing sweden and pouring rain on poland, france, and yorkshire in Britain.
The radiation released was also less than that of the Hiroshima bomb, and far less than the media has reported since. I understand that the children of chernobyl itself have been harmed however them and their mothers vicinity to the event would suggest that mutation would have happened.
The radiation from the fall out cloud wasn't that great either, some effect was noticed in sheep, but not statistically significant beyond some minor issues.
People seem to forget that chernobyl wasn't anywhere near as big as the events at the bikini atol, or the nevada desert, and also seem to forget that for the last 50 years no detrimental effect has been demonstrated on those within 500 miles of those events. They even grow Marlbro on the site of the trinity test, which was a ground level detonation and even with the fall out from that (which was in the region of half a million tonnes) hasn't caused lasting damage.
