36 Postdoctoral Fellowship at Oak Ridge National Laboratory, United States

The responsibilities of this position include using aerial detector surveys to provide a nationwide means of predicting yield from a nuclear detonation.

The research will also extend our ability to rapidly update our models based on the aerial measurement data. A sensitivity study will be performed to show the relative impact of the different types of flights that are performed by aerial systems in a graded approach (e.g., edge detection versus serpentine versus complete mapping). The selected candidate will ultimately create a yield prediction software tool using the deposition pattern measured by aerial survey equipment with a proof-of-principle demonstrated by application of the tool to known historical survey measurements, and will provide recommendations for optimal surveying strategies to minimize yield uncertainties and operational timeliness. The responsibilities of this position include conceptualizing and performing research and development in forensic evaluation of nuclear materials.
