Federal energy officials say, they're permanently closing two underground storage tanks that once held radioactive waste at the Savannah River Site near Augusta. The US built the tanks during the Cold War and started cleaning them up in the 1980's. Officials hailed the closures. But they also noted, there are 47 more such tanks that need to be made permanently safe.
The impact of radiation leaking from Japan's tsunami-damaged Fukushima Daiichi nuclear plant still isn’t clear. Near Augusta, scientists are studying another kind of radioactive contamination. It comes from decades ago, when the Savannah River Site produced the nation's nuclear weapons. Noel Brown reports on how turtles, alligators and water birds are tracking nuclear cleanup.
