The ERMIN model is a new implement developed to enable estimation of the radiological
consequences in inhabited areas of accidents in nuclear installations. Similarly, AGRICP
is a model developed to enable estimation of the radiological consequences of
contamination of agricultural production areas. This paper provides a short overview of
the background of the two models and describes the features enabled through their
implementation in the ARGOS decision support system. The integration allows calculation of
both dose rates and doses in particular areas, and can be used to evaluate the
effectiveness and costs of countermeasure strategies.
