    Uranium mining in Australia is polluting the Antarctic, about 6,000 nautical miles away.
    University of Maine climate scientists made the discovery during the first high-resolution continuous examination of a northern Antarctic Peninsula ice core.
    Ice core data reveal a significant increase in uranium concentration that coincides with open pit mining in the Southern Hemisphere, most notably Australia, says lead researcher Mariusz Potocki, a doctoral candidate and research assistant with the Climate Change Institute.
    Understanding airborne distribution of uranium is important because exposure to the radioactive element can result in kidney toxicity, genetic mutations, mental development challenges and cancer.
    Uranium concentrations in the ice core increased by as much as 102 between the 1980s and 2000s, accompanied by increased variability in recent years.
