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.

A method of studying neutron transport properties in H2O-D2O mixtures, both liquid and solid, which extrapolates the neutron thermalization parameters of H2O is described. The decay of pulsed neutrons in the media has been investigated as an example of the application of the method. The results of the calculations agree with the experiment for concentrations up to 50% D2O.
