IAEA project - MODARIA (Modelling and Data for Radiological Impact Assessments)

The general aim of the MODARIA project is to improve capabilities in the field of environmental radiation dose assessment by means of acquisition of improved data for model testing, model comparison, reaching consensus on modelling philosophies, approaches and parameter values, development of improved methods and exchange of information.

The overarching objective is to enhance the capabilities to simulate radionuclide transfer in the environment and, thereby, to assess exposure levels of the public and in the environment in order to ensure an appropriate level of protection from the effects of ionizing radiation, associated with radionuclide releases and from existing radionuclides in the environment.

Specific objectives of MODARIA project are:

  • To test the performance of models developed for assessing the transfer of radionuclides in the environment and radiological impact to man and environment;
  • To develop and improve models for particular environments and, where appropriate, to agree on data sets that are generally applicable in environmental transfer models;
  • To provide an international forum for the exchange of experience, ideas and research information.
