Six years after the Chernobyl accident, the major part of deposited radio nuclides remains in the 3 or 4 cm of the topsoil of abandoned fields in the chernobyl zone. The Decontaminating Vegetal Network allows a layer of few centimeters of the top soil to be removed with a turf harvester. The efficiency observed at Chernobyl was 97% for cesium-137 and strontium-90. After scraping the soil with the turf harvester, the bare soil must be covered and re-grown in order to prevent wind erosion of the sandy soil. A trial spraying of polyacrylamide on the soil was carried out. This technique seems promising. Trials of bio-decontamination of the removed turf using anaerobic degradation were also carried out. This experiment provided an opportunity to measure in real conditions the transfer of radionuclides in the Chernobyl zone.
