Water tested around 37 of the facilities contained radioactive concentrations exceeding the U.S. drinking water standard and in some cases at hundreds of times over the limit.
One serious case was uncovered at the Braidwood Nuclear Power Station in Illinois, which has leaked more than six million gallons of tritium-laden water in repeated leaks dating back to the 1990s. Scientists says tritium is not dangerous in small doses but prolonged exposure to high levels is believed to increase the chances of cancer, leukaemia, and mutations in humans.The leaks have been uncovered by a year-long Associated Press investigation found by trawling the U.S. Nuclear Regulatory Commission (NRC) records. Despite the revelations the NRC and industry bosses consider the leaks a public relations problem, not a public health threat. |
