Radioactive wasp nest found at site where US once made nuclear bombs

Workers at a South Carolina site that once made nuclear bomb parts have found a radioactive wasp nest. Officials say there's no danger to anyone. Employees checking radiation levels at the Savannah River Site near Aiken found the nest on July 3. It was near tanks storing liquid nuclear waste. The nest had radiation levels 10 times above federal limits. Workers sprayed it with insect killer and disposed of it as radioactive waste. No wasps were found. Officials say the nest was likely contaminated from residual radioactivity. Watchdog group Savannah River Site Watch criticized the report for lacking details on the contamination source.
