What is the definition of Nuclear Fumes?

Ah, nuclear fumes - the ol' term for the byproducts of a power plant's secretive nuclear reactor. Picture this: "The nuclear fumes from the power plant's secret lab were so toxic, they turned the local wildlife into a bunch of mutated, glow-in-the-dark, radioactive pigeons." It's like the universe decided to give us a free, albeit unpleasant, spa day in the form of a nuclear apocalypse!
