Abstract
The article presents the results of the study of plutonium migration patterns in the “soil — soil solution — plant” system based on the study of two key indicators: the value of their transition from the soil to the soil solution and the value of their absorption from the soil solution by plants. The study was carried out in a vegetation experiment using a specially designed stand. The stand included a lysimeter and allowed growing plants hydroponically on a soil solution constantly circulating in a closed cycle. The plutonium content was analyzed by the alpha spectrometric method with preliminary radiochemical isolation. The results of the study established an extremely small value of plutonium transfer from soil to soil solution. A significant difference in the plutonium uptake by different parts of plants was determined. The contribution of the root uptake complex responsible for the apoplastic pathway in the process of plutonium uptake by plants is assessed.
