The Radioactive Fish is a mutated creature which lives in the surrounding bodies of water near Pripyat. After the group enters the Chernobyl Exclusion Zone through Yuri's alternative entrance, a dead fish is found on the banks of a river. When examined closely and subsequently touched, it reacts and freaks out the group. As the group returns to the van, the camera pans on many of these fish moving or feeding rapidly in the water. Later on in the film after Paul, Michael, Amanda, and Zoe retrieve the cables needed to repair the van and are being chased by the pack of the dogs, they have to cross a flimsy wooden bridge over a river. Zoe falls into this river and Micheal goes in to help her. Afterwards, while Micheal was in the water he was attacked by what is presumably these fish.
Not much is known about these fish. However, it can be assumed that they mutated from the various forms of fish which inhabited the surrounding bodies of water that were irradiated by the Chernobyl Disaster.
