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.

Adsorption and desorption of D2O or H2O, as a simulator of HTO, on iron surface covered with thin iron oxide film were studied by thermal desorption (TD), electron stimulated desorption (ESD), photon stimulated desorption (PSD), X-ray photoemission spectroscopy (XPS), and scanning electron microscopy (SEM). When the iron was heated under constant heating rate (5K/min), adsorbed D2O was desorbed around 400K and 600K. Adsorbed D2O which could not be desorbed by heating to 773K could be desorbed by irradiation with photon or bombardment with electron.
