Chernobyl Reclaimed

I went to see a film called "Chernobyl Reclaimed", about the life around Chernobyl after the disaster. The animals have reclaimed the area immediately surrounding the Reactor. They are free to roam the area without humans to interfere with them so on the surface this must be a paradise for them. But all the animals living in the area are radio-active, the bears and the wolves, the feral cats, and the birds. The people filming had to wear protective clothing and they could stay in the area only for short periods at a time, these animals live there and get their food there. They move in and out of the area freely and they seem to be doing very well. It's a worrying thought though.
