Abstract: Images and illustrations showing diversity of radio-contamination and the difficulty to confront the problem. Systematic description of problem leads the reader towards perception of necessary renovation of international standards to establish a new scientific field – Radiation Geography.

Keywords: landscape geochemistry, anthropogenic radioactivity, topography
Abstract: Describes specification of “anthropogenic radioactivity”: takes man-made radionuclides, and its diffusion in the environment into account, which has become part of today’s landscape geochemistry. Includes collection of drawings of radioactive traces, classified by type of formation, which gives an idea of the possible configurations and extent of contamination. The role of topography is observed in a new aspect – characteristics of erosional dissection.

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 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 [, , , , , , , , ]and 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.
