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 effect of low-energy neutrons on activation cross-section measurements was analyzed carefully and proved by the measured neutron spectra of T(d,n)4He and D(d,n)3He reactions. The 58Ni(n,p)58m+gCo and 64Zn(n,p)64Cu reactions were used to confirm this analysis, and their cross sections were measured accurately. In addition, their evaluated excitation functions are given.
