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.

Transmutation of elements in Pd hydrides with gas loading instead of liquid electrochemistry has been observed. The number of elements found increased for deuterated Pd samples processed with an XeCl excimer laser. The processing times were less than and more than 60 days, and some samples became incandescent when they were put into contact with air. The Pd-processed samples were analyzed with a scanning electron microscope and an electron probe microanalyzer; many pits on the surfaces of the samples were found along with the transmutation of many elements - Al, Au, C, Ca, Fe, Mg, Na, Nd, Ni, O, S, and Si - while the quartz windows, utilized to seal the cell, presented Al, C, Ca, Cl, K, Mg, Na, Ni, S, V, and Zn. Elements were also found, when the cross sections of the Pd samples were analyzed (particularly at a few micrometres from the external surface), that corresponded to the pits. Analysis of the samples that were processed less than 60 days showed that the highest X-ray peak was due to an Al-K emission line, and its intensity was 40% with respect to the Pd-L peak. In samples processed at 60 days, the Al concentration decreased while the Si-K, Fe-K, and O-K emission lines increased, resulting in the highest emission line, and their intensities were 50, 40, and 30%, respectively, with respect to the Pd-L peak.
