DTRA’s advancements in nuclear and radiological detection
A new, more complex nuclear age has begun. Echoing the tensions of the Cold War amid rapidly evolving nuclear and radiological threats, preparedness in the modern age is a contest of scientific innovation. The Research and Development Directorate (RD) at the Defense Threat Reduction Agency (DTRA) is charged with winning this contest.

The differential elastic- and inelastic-scattering cross sections of 10B, 11B, natural Ge, and 93Nb have been measured at incident neutron energies of 7.02 and 7.55 MeV for 10B; 7.55 MeV for 11B; 7.55 MeV for Ge; and 5.95 and 7.47 MeV for 93Nb. The cross sections were measured with a neutron time-of-flight spectrometer relative to the cross section for neutron scattering from hydrogen.
