Gofman used his low-level radiation health model to predict 333 excess cancer or leukemia deaths from the 1979 Three Mile Island accident . Studies of the health effects of the Three Mile Island accident have so far ( by 2013 ) not observed any excess mortality . A retrospective study of Pennsylvania Cancer Registry found an increased incidence of thyroid cancer in counties south of TMI and in high-risk age groups . The Talbott lab at the University of Pittsburgh reported finding only a few , small , mostly statistically non-significant , increased cancer risks within the TMI population . However , excess leukemia among males was observed . The ongoing TMI epidemiological research has been accompanied by a discussion of epidemiological methodology , such as problems in dose and illness classifications
