Exposure to high concentrations of radon progeny (radon) produces lung cancer in both underground miners and experimentally exposed laboratory animals. To determine the risk posed by residential radon exposure, the authors performed a population-based, case-control epidemiologic study in Iowa from 1993 to 1997. Subjects were female Iowa residents who had(More)
OBJECTIVE To delineate the frequency, course, risk factors, and neuroanatomy of hemispatial neglect in a large stroke cohort.
