Description: Das Projekt "Spatial and temporal radio ecological survey system" wird vom Umweltbundesamt gefördert und von GSF - Forschungszentrum für Umwelt und Gesundheit GmbH, Institut für Strahlenschutz (ISS) durchgeführt. General Information: the explosion at the Chernobyl nuclear plant in April 1986 affected Large areas of in Central and Eastern Europe. Research carried out in the Rovno region, in the northwest Ukraine, some 350 km west of Chernobyl, demonstrated a strong relationship between radiation levels and land use, soil type, the incidence and extent of flooding. After the flood of 1993, 137Cs concentrations in the top soil of the floodplains were found to be up to three times higher than just after the Chernobyl accident. However, in 1994 the concentrations were almost back to level of before flooding. A preliminary analysis of temporal changes in the 137Cs levels in the flooded areas, suggests that these levels are enhanced by two major pathways: through deposition of contaminated suspended matter and/or through direct uptake from the flood water by submerged plants. Understanding of the contribution of these pathways to contamination of riverine ecosystems is essential for assessment, management and restoration of contaminated territories. Achievements: Foreseen Results This project has four aims: (i) to get a better understanding of the hydrochemistry of 137Cs in flood water by collection of field data which will allow for data processing using geostatistical techniques and Geographical Information Systems (GIS) (ii) to exchange knowledge and to train the collaborators in geostatistical methods for spatial and temporal sampling and monitoring, remote sensing, and GIS-based modelling, so that implementing the EDSP can be carried out (iii) to implement the EDSP in the NIS countries. The EDSP will be tested and applied to existing databases of the radiation situation in the Chernobyl accident areas, already available in the NIS countries (iv) to demonstrate the use of modern advanced information technologies as GIS, geostatistics, and remote sensing to improve the data analysis of radioactively contaminated areas.
