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.

Hydrogen diffusivity and solubility in Inconel 600 were determined with a gas-absorption method using tritiated hydrogen gas in a temperature range from 573 K to 973 K. The temperature dependence of diffusivity D and solubility S were obtained as,D (cm2s−1) = 1.3 x 10−2 exp(−50.6/(RT / kJ)),S (cm3(NTP)cm−3Pa−0.5) = 4.7 x 10−3 exp(−11.7 /(RT / kJ)).
