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 exchange of CH4 in tritium has been measured at concentrations of 1.45 and3.00 mol% to display the time evolution of CT4. It is observed that the total methane concentration decreases with time, and no masses >24 amu are observed using mass spectroscopy. After 18 months, only 0.2% CT4 gas remained in the 3.00% CH4 experiment. These observations indicate that carbon is being removed from the gas phase. A model based on ion/molecule interactions is presented to explain the formation of CT4 and free carbon.
