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.

At Tritium Laboratory Karlsruhe (TLK) calorimetry is used as the primary method for tritium accountability and for samples ranging from micrograms to tens of grams. An accuracy of 0.3% is achievable for samples containing more than 0.5 mg tritium and the precision of each calorimeter is better than 0.5%. The results of the TLK calorimeters vary within maximum 0.6% from each other.
