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.

The minimization of the functionals defined by the prior knowledge and integral data of a neutron spectrum can be the basis of many unfolding methods. The form of these functionals classifies the widely used methods: FERDOR, SPECTRA, RFSP, CRYSTAL BALL, SAND-II, STAYSL, and others. The methods are systematically derived and theoretically compared to each other. Their relations to the function expansion method are discussed, and several cases of estimated spectra are studied. Treatments of response-function errors are also mentioned.
