(AP) — About a quarter of Navajo women and some infants who were part of a federally funded study on uranium exposure had high levels of the radioactive metal in their systems, decades after mining for Cold War weaponry ended on their reservation, a U.S. health official Monday. > The preliminary findings from the University of New Mexico study were shared during a congressional field hearing in Albuquerque. Dr. Loretta Christensen — the chief medical officer on the Navajo Nation for Indian Health Service, a partner in the research — said 781 women were screened during an initial phase of the study that ended last year.
