I would assume they were playing too much of the S.T.A.L.K.E.R. Series[1] or used it as source when writing the article title. Even half suggesting that animals would glow is link bait and just silly. I mean, it's not like animals glowed after the atomic attacks on Japan or anywhere nuclear weapons have been tested. Granted that there's differences in the radiation, but still it's kind of specious reasoning.
The title is stupid, but I liked the article. I would be happy if the submitter changed the title here to something more accurate like "Current State of the Animals Chernobyl’s Fallout Zone".
