Not really. They're uninhabitable only because of not-always-rational fear of radiation. People were fleeing from Japan because of Fukushima, and when doing so some of my countrymen returned here, where the natural background radiation is higher than in the affected area they ran away from.

Fukushima exclusion zone is a social phenomenon created by human fear, not physiological created by radiation.
