Reiterating your point, the area is uninhabitable on a timescale of thousands of years. Some estimates are at 20,000 years. The timeline of that region being poisonous extends so far beyond our current history that it's effectively permanent.

What happens when the Chernobyl confinement deteriorates every hundred years or so, and eventually nobody is around to maintain it anymore.
