Nature is doing great around Chernobyl. The vegetation came back, it never left anyway. Plants can take high radiation. But the mammals and other animal life came back long ago. I don’t know if the radiation is down enough to be safe for people. And perhaps the soil is polluted with radioactive debris within a certain radius and depending on prevailing winds. So can you eat vegetables and fruits grown near the old blown reactors? Can you eat the meat of your grazing animals, goats, sheep, cattle? Drink their milk?
Many people have moved back to their old villages in the area. Wild animals have flourished and plants have done well. The issue is the long term effects of the residual radiation.
