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.

Neutron capture up to 700 keV was measured for arsenic and bromine and for an enriched sample of 81Br. Individual resonance capture was parameterized in the first several kilo-electron-volts and average capture cross sections derived at the higher energies. Maxwellian average cross sections found for 79,81Br and 75As, respectively, were 741 ± 30, 244 ± 10, and 455 ± 18 mb for a temperature kT = 30 keV. Resonance capture integrals calculated for 79,81 Br, respectively, were 130 ± 5 and 46.6 ± 1.8 b.
