Why is all the radiation gone from Nagasaki and Hiroshima but not Chernobyl? I know Chernobyl was more recent but I've heard Nagasaki and Hiroshima's radiation was cleaned up fairly quickly.
Here's a thing. Restrictions on the sale and movement of sheep in North Wales, UK were only lifted in 2012, twenty six years after the disaster.
North Wales is over 1500 miles from Chernobyl.
It's hard enough making a living as a hill farmer in the principality anyway. All farmers could do was raise sheep for slaughter and destruction, for the measly government compensation, nothing else can be farmed there (apart from a few game birds).
People died as a consequence of Chernobyl's technical inadequacies, and I guess that is why so little fuss was made over whole bunch of sheep.
