heal.abstract	Immediately after the Chernobyl accident, a soil sampling programme was undertaken in order to detect and quantitatively analyse the long-lived radionuclides in the Chernobyl fallout. Soil samples (1242 in number) of 1 cm thick surface soil were collected in Greece during the period from May-November 1986. The samples were counted and analysed using Ge detector set-ups. The Cs-137 fallout data have already been analysed, mapped and published. In an attempt to improve this analysis and also to extend it to other fallout radionuclides, an in-house unix-based data base/geographical information system (DBGIS) was developed. Multifractal analyses of the deposition patterns have also been performed. In the present work, an analysis of the results of the deposition of Cs-137, Cs-134, Ce-144, Ce-141, Sb-125, Ag-110m, Ru-106, Ru-103, Zr-95 and Mn-54 are presented together with relevant fractal analysis and three characteristic contour maps. The maximum detected values of the above-mentioned radionuclides were 149.5+/-0.1, 76.1+/-0.1, 32.9+/-0.2, 46+/-2, 4.56+/-0.02, 7.98+/-0.02, 79.1+/-0.4, 337+/-2, 20.1+/-0.2 and 3.02+/-0.02 kBq m(-2), respectively. Furthermore, a statistical technique to compare contour maps was introduced and applied to explain the differences which appeared in the maps of the above-mentioned radionuclides.
