|Abstract:||Radionuclides emitted from the Fukushima I nuclear power plant have been detected in air all over Europe. Concentrations remained far below levels which could have caused radiological concern. They provided, however, a spatio-temporal signal which could be used to develop and test tools to could provide additional information on the large-scale situation (Europe-wide, in this case) during a nuclear emergency. In part one we discuss the spatial distribution of the contaminated air masses over Europe. Using 131I as an example, we present a method to construct maps of the cumulated 131I concentration in air and of the peak concentrations. Procedures to deal with the statistical limitations of a data set stemming from different monitoring schemes are discussed. We suggest to consider such methods of data harmonisation if synoptic assessment based on heterogeneous datasets is attempted.|
