Okay
Pripyat, Ukraine may be a ghost town but for all intents and purposes is now a wild life sanctuary where apex predators roam free and live healthy lives right on the grounds of the Chernobyl power plant. Birds and bats nest inside the Chernobyl sarcophagus and appear to suffer no ill effects.
Hiroshima is a thriving city populated by people indiscernible from other people in Japan.
What this tells me is that relatively high levels of radioactive contamination and chronic radiation exposure can be tolerated with little or no ill effects.
Your “Facts” are inaccurate as it was recently reported that there are serious problems with mutations of wild life in that are. But why don’t you just go there and pitch a tent for a couple of years and show us how safe it is.
