  • Title: Modeling of the EMRAS urban working group hypothetical scenario using the RESRAD-RDD methodology.
    Author: Kamboj S, Cheng JJ, Yu C, Domotor S, Wallo A.
    Journal: J Environ Radioact; 2009 Dec; 100(12):1012-8. PubMed ID: 19403213.
    Abstract:
    The RESRAD-RDD methodology was applied to model the short- and long-term radiation exposures after a hypothetical radiological dispersal device (RDD) event in an urban environment. It was assumed that an RDD event would result in outside surface contamination of the exterior walls and roofs of surrounding buildings, as well as associated paved areas and lawns. The contaminants also might move inside the buildings and deposit on floors and interior walls. Some important input parameters include occupancy factors, building characteristics, and weathering of surface contamination. The modeling results include predicted external dose rates, relative contributions from important surfaces, annual and cumulative doses, and radionuclide concentrations. Potential countermeasures evaluated include grass removal, soil removal, and washing of paved areas.
