I just finished "The Last Oracle" by James Rollins which takes place in part in Pripyat and Chernobyl. Curse You coincidince! Or possibly Great Job coincidince!
A clip of a perfectly healthy looking kitty and some equally healthy looking big fish swimming around does not lend to the narrative about the horrors of radioactive fallout.
At this point you could probably live there without a problem but your chance of dying much younger due to fallout related disease is probably a lot higher than normal
Those fish are catfish, which you'd expect to survive a nuclear disaster. They're pretty much the last fish to die in any scenario. Worse yet, catfish are already on the evolutionary brink of crawling out of the water and biting us.
