COLUMBIA, S.C. (AP) — Workers at a site in South Carolina that once made key parts for nuclear bombs in the U.S. have found a radioactive wasp nest but officials said there is no danger to anyone.

An analysis found the wasp nest's contamination level to be "greater than 10 times the total contamination levels" set in federal regulations.

Workers discovered a radioactive wasp nest near tanks storing liquid nuclear waste. Officials say there’s no need to panic, but watchdog groups are skeptical.
