Radioactive wasp nest found at old US nuclear weapons site

A radioactive wasp nest with ten times the allowed radiation levels was found at the Savannah River Site in South Carolina. The nest was discovered near liquid nuclear waste storage tanks, but no leak was reported. The contamination is believed to be from the site's past production of parts for nuclear weapons during the Cold War. Although there were no impacts to the environment or public, questions remain about the source of the radioactive waste.
