Abstract: | The aim of the study reported in this paper was to derive factors describing the translocation of radiocesium from the green
plant parts to the crop. Wheat, rye and potatoes were contaminated and harvested at different growth stages to allow the assessment
of the contamination of the crop with known date of the radioactive deposition. At harvest, the cesium concentrations in the
crop, the green plant parts (i.e., straw without ears) and the roots were measured. The results show that the contamination
of the crop depends strongly on the date of134Cs application and on the type of plants. The highest translocation was observed when cesium was applied during flowering. |
