So there's a bushfire somewhere and you immediately flip out about it...?
Basically the news story is "bushfire happens in dry wooded area that happens to be near an area of interest because 30 years ago a nuclear reactor leak occurred there."
I don't know exactly what the OP is insinuating (That the vast area around Chernobyl is still dangerous and Russia, despite the fact that the area is in the Ukraine, is cooking the books on it somehow, despite years of research and data saying otherwise?) but I fail to see how even that is relevant to the situation at hand.
