A new study of people living downwind of the nuclear weapons test site in Nevada finds thyroid damage was more extensive than previously believed.
Dr. Joseph Lyon of the University of Utah and his colleagues re-examined data from a 1993 study, the Deseret Morning News reported. Lyon found that thyroid damage was more extensive than the original study reported.
The Centers for Disease Control canceled another Lyon study in March 2005.
Lyon said that he and his colleagues were more conservative in their diagnostic criteria than the scientists who did the 1993 report. But they discovered an even stronger correlation between thyroid abnormalities and exposure to radiation.
The study is to appear in the November edition of Epidemiology.
