Abstract/Summary

Radiocaesium is an important and persistent environmental contaminant that can be deposited f o l l o w i n g nuclear accidents. It became apparent after the Chernobyl accident that some regions were vulnerable to radiocaesium deposition. Prior identification of vulnerable areas using spatial models that incorporate variation i n radiocaesium soil-to-plant transfer as a function of soil properties would allow post-accident management options to be prioritised and effectively implemented. In this paper, an assessment of the influence of different input soil property data sets for Hungary upon spatial model predictions of cow milk 1 3 7Cs activity concentrations and the identification of vulnerable areas is presented. Although predictions of cow m i l k 1 3 7Cs activity concentrations after Chernobyl made using the three input soil property data sets are all broadly similar and i n reasonable agreement w i t h national monitoring data, the identification of vulnerable areas is greatly influenced by the input soil property data set used. Our results suggest that using soil property databases derived f r om amalgamation of soil properties into broad soil categories w i l l lead to vulnerable areas not being identified. The findings presented i n this paper have important implications for the use of spatial models i n the prediction of radiocaesium transfer, identification o f vulnerable areas and management o f contaminated areas.
