• The History of Uranium Mining and the Navajo People

    THE CAUSAL AGENT FOR LUNG CANCER. Although it was unknown to the Navajo People by the late 1930s there was no scientific doubt that uranium mining was associated with high rates of lung cancer.24 The debate was about the causal agent. A ventilation project begun in Jachimov Czechoslovakia by the Ministry of Public Works in 1930 provides clear evidence that policymakers at the time thought
