The first published study to focus on the abundance of animal populations within the 36-mile diameter “dead zone” contradicts some earlier science-light research largely promoted by the International Atomic Energy Agency (IAEA) that suggested wildlife populations were dramatically rebounding and that the radioactive abandoned landscape is actually a “nature reserve” for wolves, bison and bears. The more recent study by Moller and Mousseau published findings that the radioactive fallout has significantly depleted biological species including birds and insects. Moller and Mousseau also found “a high incidence” of deformed animal species.
