Chernobyl's blue dogs spark radiation theories, but expert Timothy Mousseau shares "likely" cause behind colorful canines spotted roaming exclusion zone.

Poo-dunnit? Stray dogs living in the Chernobyl exclusion zone whose fur turned bright blue likely got their color from rolling in a tipped-over porta-potty, according to local animal volunteers. The periwinkle pooches went viral in October after pictures of three dogs with blue fur were shared on Facebook by the Dogs of Chernobyl program,

The blue dogs spotted at Chernobyl are not blue because of radiation but rather because they rolled in porta potty chemicals, according to a scientific advisor for Dogs of Chernobyl.

Bizarre changes in animal behaviour and appearance have unfolded at the highly reactive Chernobyl site in the 40 years since the disaster - including 'evolving' dogs and cancer-resistant wolves

These wild horses were introduced to the Chernobyl Exclusion Zone in 1998 as part of a "rewilding experiment."

They’re not turning blue. But are the stray dogs roaming Chernobyl’s radioactive wasteland undergoing rapid evolutionary change?

The protective shelter built to contain radioactive material from the 1986 Chernobyl disaster can no longer block radiation after an attack by Russia. A suspected Russian drone hit the power plant in northern Ukraine earlier this year, starting a fire in the outer cladding of the massive steel structure.

Research has found a black mold has been growing toward and surviving on the ionizing radiation at the Chernobyl nuclear power plant.
