Chernobyl. Ukraine
Never mind the conflict currently being played out in The Ukraine, and which in all likelihood is bound to worsen, the worst thing that can befall the unsuspecting tourist is radiation poisoning from the Chernobyl Nuclear Power Plant. The 1986 nuclear disaster at the plant forced Soviet authorities to evacuate the towns of Chernobyl, Pripyat and the neighboring communities, leaving the area virtually uninhabited and a wasteland. Some former residents have returned and there are guided tours of the area, even though the area is still brimming with radioactivity.
