The Nuclear Regulatory Commission ( NRC ) has a factsheet that outlines 6 different studies . In 1990 the United States Congress requested the National Cancer Institute to conduct a study of cancer mortality rates around nuclear plants and other facilities covering 1950 to 1984 focusing on the change after operation started of the respective facilities . They concluded in no link . In 2000 the University of Pittsburgh found no link to heightened cancer deaths in people living within 5 miles of plant at the time of the Three Mile Island accident . The same year , the Illinois Public Health Department found no statistical abnormality of childhood cancers in counties with nuclear plants . In 2001 the Connecticut Academy of Science and Engineering confirmed that radiation emissions were negligibly low at the Connecticut Yankee Nuclear Power Plant . Also that year , the American Cancer Society investigated cancer clusters around nuclear plants and concluded no link to radiation noting that cancer clusters occur regularly due to unrelated reasons . Again in 2001 , the Florida Bureau of Environmental Epidemiology reviewed claims of increased cancer rates in counties with nuclear plants , however , using the same data as the claimants , they observed no abnormalities
