The nest with 10 times more radiation than permitted was found at a facility that once produced parts for US nuclear weapons.

A terrifying discovery was made at a nuclear facility in South Carolina: radioactive wasps. Radiological Control Operations found a wasp nest on a post close to a tank at the Savannah River Site in Aiken, according to a report from the U.S. Department of Energy.

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