The news is abuzz with recent news stories about four radioactive wasp nests found at the Department of Energy’s Savannah River Site in South Carolina. The site has been undergoing cleanup operations since the 1990s related to the production of plutonium and tritium for defense purposes during the Cold War. Cleanup activities are expected to continue into the 2060s.

According to a statement from Savannah River Mission Completion, which manages the clean-up operations at SRS, the contaminated nests pose no threat beyond the site, because the wasps typically do not fly outside the property boundaries.

DOE report: The first radioactive wasp nest was reportedly discovered on July 3 during routine monitoring activities at SRS on a stanchion near a nuclear waste storage tank. Three additional radioactive nests were later found. A DOE report on the first nest stated that the ground and surrounding area showed no signs of radioactive contamination, but the report did not disclose the amount of radiation detected in the nest other than noting that the level was more than 10 times the federal regulation limit.

The report concluded that following site review and testing, no further action was required in the field. “There is no impact from event on other activities and operations,” the report noted.
