Interesting.
Of course, my first thought reading this was, which camera would I take to visit such a place? I came up with 3 essentials. The Blad, as it is of similar age to Chernobyl. I persuaded myself that such a machine will encourage thoughtful composition and due justice to such a place. The Leica R8 with the 35-70 zoom (yeah, yeah - not an M with a prime. But I think a zoom at a place like this might be tactically advantageous). Both loaded with moody B&W for dark, threatening shadows. And a pocket digi for bourgeois, decadent colour. Everybody loves a radioactive bumper car in Velvia-like colour.
