Uravan Uranium Mill Dose Reconstruction

Description

Develop a CALPUFF atmospheric dispersion model application of the former Uravan uranium mill in western Colorado. Install meteorological monitoring equipment in canyon and mesa locations to delineate wind flow, and use in conjunction with other data in a CALMET simulation of the domain. Integrate atmospheric transport modeling into an overall comprehensive model to evaluate exposure and radiological dose with uncertainty to Uravan residents from stacks and tailings pile releases over a 49-year period.
