Knowledge Database and Regionalization of JRODOS for the HARMONE Project

The first part of this paper discusses the knowledge database generated for remediation
options in inhabited areas and food production systems regarding to baseline scenarios in the
area of nuclear risk management. By using a web-based decision support system ([1]) the
database provides the users with generic strategies on the basis of different contamination
levels. The strategies have complete information about the effects when taking specified
emergency response measures on various protection targets. The second part of the paper
defines the regionalization which crosses European country borders and divides Europe into
five generic radioecological regions, namely Boreal, Continental, Atlantic, Mediterranean and
Alpine regions. The parameter sets for these regions are updated in the Java based Real-time
On-line Decision Support System JRODOS ([2]). The sets include region dependent model
parameters such as agricultural yields, food consumption rates or feeding habits of livestock,
to improve the terrestrial food chain and dose module FDMT. The comparison of model results
for radionuclide activities in different food types shows pronounced differences between the

radioecological regions for several release scenarios. The work was supported by the EU
project, OPERRA-HARMONE: Harmonizing Modelling Strategies of European Decision
Support Systems for Nuclear Emergencies.
