No impact from Savannah River radioactive wasps
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.

Total 4He production cross-section measurements have been made for 6Li and 7Li for 15-MeV neutrons. Isotopically enriched samples of lithium metal were bombarded with an intense flux of T(d,n) neutrons from a rotating target neutron source. Following the irradiation, the accumulated 4He was determined by isotope-dilution mass spectrometry. The lithium samples and the incident neutron spectrum were accurately characterized, both by experimental methods and by calculational simulations. The measured 4He production cross sections are 0.512 ± 0.026 b for 6Li and 0.336 ± 0.016 b for 7Li, at an average neutron energy of 14.95 MeV.
