Wasps living around a Cold War-era nuclear facility in South Carolina have built at least four radioactive nests, raising questions about their source of hazardous material and the extent of environmental contamination, according to a report by The New York Times.
Last week, news broke that officials at the site—Savannah River Site (SRS) near Aiken, South Carolina—had found one radioactive nest on July 3. The discovery was documented in a July 22 report by the US Department of Energy, which owns the site.
The report said that the nest was on a post near a tank used to store nuclear waste and that it “was probing 100,000 dpm/100 cm2 beta/gamma.” This contamination level “is greater than 10 times the total contamination values” listed in federal regulations for areas that require contamination posting and monitoring, the report said. Still, it concluded that the radioactivity of the nest was considered to be from “onsite legacy radioactive contamination not related to a loss of contamination control.”
