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 thermal-neutron capture cross section of Ce140 and its resonance capture integral, measured by an activation method, have been found to be 0.59 ± .06 barns and 0.48 ± .05 barns, respectively. The effective capture cross section of Ce141 in the Materials Testing Reactor was found to be 29 ± 3 barns. This value was determined by mass analysis for the neutron-induced Ce142.
