A Predictive Model for a Radioactive Contamination in an Urban Environment and Its Performance Capability to the EMRAS Project

A model, called METRO-K, has been developed for a radiological dose assessment due to a radioactive contamination for the Korean urban environment. The model has been taking part in the Urban Remediation Working Group within the IAEA's EMRAS project to provide an opportunity to compare the modeling approaches and the predictive results of models that describe the behavior of radionuclide in an urban environment. The modeling approaches of METRO-K and the predictive results that have been carried out as a part of the Working Group's activities are presented and discussed. Contribution of contaminated surfaces to absorbed dose rates revealed a distinct difference for the locations of a receptor.
