Chernobyl disaster due to the ballooning in costs for new nuclear reactor safety system standards and the legal costs in dealing with the increasingly hostile/anxious public opinion, there was a precipitous drop in the rate of new startups after 1986. The accident also raised concerns about the cavalier safety culture in the Soviet nuclear power industry, slowing industry growth and forcing the Soviet government to become less secretive about its procedures. The government coverup of the Chernobyl disaster was a catalyst for glasnost, which "paved the way for reforms leading to the Soviet collapse". On 26 April 1986, at 01:23 (UTC+3), reactor
Effects of the Chernobyl disaster levels of radiation have statistically significantly smaller brains, which has shown to be a deficit to viability in the wild. Barn swallows ("Hirundo rustica") that live in or around Chernobyl have displayed an increased rate of physical abnormalities compared to swallows from uncontaminated areas. Abnormalities included partially albinistic plumage, deformed toes, tumors, deformed tail feathers, deformed beaks, and deformed air sacks. Birds with these abnormalities have a reduced viability in the wild and a decrease in fitness. Moeller et al. claimed in 2007 that these effects were likely due to radiation exposure and elevated teratogenic effects of radioactive isotopes in
