Deposition of the radiocaesium in soil at the Black Sea coastal area in Turkey after the Chernobyl accident
[en]It was known that some of the Black Sea region received rainfall containing radioactive material after the Chernobyl accident. This region was the most affected area by wet deposition because rainfall occurred during radioactive cloud passage. The unfortunate event at Chernobyl is a unique accession for better defining the fate of radioactive pollutant in the environmental. Several papers have been published recently concerning radioactivity levels observed in part of Europe and Black Sea region as a consequence of the Chernobyl accident. Indeed, the environmental central of Black Sea and its Turkish coast is of particular interest owing to the relative proximity of Turkey to Chernobyl. Not much information for the deposition rates of cesium radionuclides in soil of this area is available. Exceedingly high Cs-migration rates of 0.2-0.3 cm.h-1 in soils were found few days after deposition during a rain shower. However generally the deposited Cs was quickly fixed in the top soil and Cs migration agricultural soils decreased to values below 1 cm.a-1, levels which are known from the global fallout caesium. The fallout of radiocesium after the Chernobyl accident has renewed interest in its environmental behaviour. How it behaves in soils is important, for example, for the modelling of radiocesium transport and retention in soil and transfer from soil to plants and hence in to the food chain
