This basic observation has inevitably raised public concern as to whether the normal operation of nuclear power facilities presents an increased risk of cancer to those who work in such facilities, or who are residents near them. This concern has been heightened by recent studies from the United Kingdom that have reported excess incidence of childhood leukemia in children living near several nuclear facilities, most notably a fuel reprocessing plant located at Sellafield in northwest England.³

To estimate the cancer risks associated with exposure to low doses of radiation, the usual procedure is to extrapolate the results of high-dose studies, such as that . . . [Full Text PDF of this Article]
