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.

ETDOSE is a simple computer code for calculating distribution patterns of tritium in the environment for acute and chronic releases of HT and HTO. It calculates tritium concentrations in air, soil, plant free water and plant organic material, and estimates dose impacts from inhalation of air and ingestion of food. ETDOSE includes two different models for calculating HTO re-emission from the soil surface for a chronic tritium release. These two models were tested in the IAEA's model validation program BIOMASS (BIOsphere Modeling and ASSessment methods)1.
