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.

Experimental data of 54Fe(n, 2n) cross sections below 20 MeV were analyzed and evaluated with corrections and normalization. The data were processed in terms of a fitting by a spline code with the consideration of correlation errors. Also, the corresponding covariance matrices of the experimental data were constructed with the information on experimental errors and correlation errors.
