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 cross sections on carbon at and above 14 MeV are of interest for a variety of applications. It is argued that the ENDF/B-V evaluation of the nonelastic cross sections is in some error; this is due in part to the “subtraction” technique used for evaluating the nonelastic cross section, and to an overreliance on old nuclear emulsion data. In addition, secondary uncharged- (and, for biomedical applications, charged-) particle spectra are important. It is shown that kerma-factor calculations are very sensitive to the secondary charged-particle spectrum. Thus an assessment of the reaction mechanisms, leading to evaluated secondary particle spectra, is also needed.
