The Department of Energy said radiation contamination levels on the wasps' nest were over 10 times the regulated maximum.

Personnel monitoring radiation levels at Savannah River Site, a facility in South Carolina that once produced parts for nuclear weapons, found a radioactive wasp nest in July. While this might sound like the start of a science fiction horror movie, officials say it does not present a danger to the public.
