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 capture and fission probabilities of U238 have been determined radiochemically as functions of horizontal position in EBR-I (Mark II). The ratios σc(U238)/σf(U235) and σc(U238)/σf (Pu239) are also presented as functions of horizontal position in the reactor.
