The effects of low-level radiation on human health are not well understood, and so the models used, notably the linear no threshold model, are open to question. [105] Given these factors, studies of Chernobyl's health effects have come up with different conclusions and are sometimes the subject of scientific and political controversy.
A study analyzed the DNA of feral dogs living near Chernobyl, compared the animals to others living 10 miles away, and found remarkable differences.
Rival packs of stray dogs scavenging for scraps around the Chernobyl fallout zone may be evolving faster than other animals to survive in one of the most hostile environments on Earth.. Scientists ...
A dog in the Chernobyl exclusion zone, 2017. The exact origin of the populations of dogs living in the Chernobyl Nuclear Power Plant (CNPP) and the surrounding areas of the Chernobyl Exclusion Zone is unknown. [1] However, it is hypothesized that these animals are the descendants of pets left behind during the original evacuation of Pripyat.
Now, approaching 40 years since the disaster, scientists are exploring how the explosion and subsequent exposure to radiation may have impacted on the evolution of the animals living nearby.
Hyperthyroidism, stunted growth, and, of course, death plagued the animals left on the island. [9] The loss of human population in Chernobyl, sometimes referred to as the "exclusion zone," has allowed the ecosystems to recover. [9] The use of herbicides, pesticides, and fertilizers has decreased because there is less agricultural activity. [9]

For example, the study of environment, animals and plants around the Chernobyl disaster area has revealed an unexpected survival of many species, despite the high radiation levels. A Brazilian study in a hill in the state of Minas Gerais which has high natural radiation levels from uranium deposits, has also shown many radioresistant insects ...
