A population of wild dogs living near the Chernobyl exclusion zone is now giving scientists a glimpse into how long-term radiation exposure affects generations.

March 3, 2023, 2:49 PMChernobyl dogs live in a variety of habitats throughout the nuclear exclusion zone including forested areas around Pripyat and Chernobyl City.is now giving scientists a glimpse into how long-term radiation exposure affects generations.

A pack of free-roaming dogs that lives within the industrial areas of the Chernobyl Nuclear Power Plant.The dogs still living around the exclusion zone are likely descendants of pets left behind after residents surrounding the Chernobyl power plant fled the region in a hurry, leaving behind all their belongings, including their four-legged companions, Tim Mousseau, a professor of biological sciences at the University of South Carolina, told ABC News.

Many of the Chernobyl dogs find shelter in abandoned buildings or construction zones within the nuclear exclusion zone.Scientists are also looking for other developmental abnormalities, such as tumors, smaller brain sizes and changes in symmetry, Mousseau said. Chernobyl dogs living outside the New Safe Confinement Structure, which was built to contain radioactivity from the explosion of reactor four.Although exposure to ionizing radiation is known to elevate genetic mutation rates across various plant and animal species, it is still unclear how larger animals may be impacted at the population level, according to the study.
