In response, the Homeowners Association conducted a health survey headed by Gibbs and Dr. Beverly Paigen, a Roswell Park cancer research scientist. The survey, conducted outside the government’s evacuation zone, found that 56 percent of the children born in the neighborhood between 1974 and 1978 had significant birth defects. The survey also found an abnormally high number of miscarriages, crib deaths, epilepsy, urinary tract disorders and other significant health problems.
