Models and Measurements: Complementary Tools for Predicting Atmospheric Dispersion and Assessing the Consequences of Nuclear and Radiological Emergencies [open pdf - 496KB]
"Since its inception over 26 years ago, NARAC (the National Atmospheric Release and Advisory Center) has used measurement data to update model predictions of radioactive releases from known origins. NARAC continues to routinely participate in emergency response drills with organizations that collect air concentration, ground deposition, and radiation exposure measurements. From a complementary perspective, NARAC is now developing an advanced capability to combine models and data from monitoring systems to characterize and forensically reconstruct atmospheric release events of unknown origin."
