The IAEA organized a programme from 2012 to 2015 entitled Modelling and Data for Radiological Impact Assessments (MODARIA), which aimed to improve capabilities in the field of environmental radiation dose assessment by acquiring improved data, model testing and comparison of model inputs, assumptions and outputs, reaching a consensus on modelling philosophies, aligning approaches and parameter values, developing improved methods and exchanging information. This publication describes the activities of Working Group 2, Exposures in Contaminated Urban Environments and Effect of Remedial Measures.

Times Cited Count:9 Percentile:52.81(Chemistry, Inorganic & Nuclear)The IAEA's model evaluation program EMRAS (Environment Modelling for Radiation Safety) includes a Tritium and C-14 Working Group (TCWG), the goal of which is to test the performance of environmental tritium and C-14 models. The TCWG has undertaken nine scenarios in which model predictions were compared with experimental data. Two of these scenarios are discussed here, one involving the prediction of time-dependent tritium concentrations in freshwater mussels subject to an abrupt change in ambient tritium levels, and the second involving the prediction of C-14 concentrations in rice grown in the vicinity of continuous atmospheric C-14 sources.
