CCTV captures Chernobyl nuclear plant damaged by Russian drone
Images of dogs with blue fur in the Chernobyl nuclear exclusion zone circulated in October, prompting various theories.
Initial speculation suggested the blue colour could be linked to high radiation levels or an evolutionary adaptation to the environment.
Scientists have since debunked these claims, attributing the blue dye to the dogs rolling in faeces from a tipped-over portaloo.
University of South Carolina scientist Timothy Mousseau confirmed the colouration was more likely a result of the dogs' “unsanitary behaviour” and not a mutation or radiation effect.
The dogs are descendants of pets abandoned after the 1986 nuclear disaster, with their welfare now managed by the Clean Futures Fund's 'Dogs of Chernobyl' programme.
