This study presents the results of a model experiment with Picea abies determining the role of root exudates in the intake of radiocaesium into soil solution. It has been established that the amount of consumed ¹³⁷Cs depends on the weight of the root system, with the majority of the radionuclide presumably accumulating in the primary cortex of the root; i.e., it was not redistributed further between the structural components of the plant. The amount of ¹³⁷Cs entering the aerial part is approximately 2.5% of its total storage in the plant. During the experiment (7 days), 37.4–53.8% of the radionuclide accumulated in the assimilating organs were transported into pure solution with root exudates and the radiocaesium storage transported into the solution exceeded that of the roots. The movement of ¹³⁷Cs in the aqueous film on the surface of the root systems have not been recorded.

模型试验中挪威云杉根分泌物营养液中137 Cs摄入的一些指标。

这项研究提出了与云杉云杉进行的模型实验的结果，该实验确定根系分泌物在土壤溶液中吸收放射性铯的作用。已经确定消耗的¹³⁷ Cs的量取决于根系的重量，其中大多数放射性核素可能聚集在根的初级皮层中。也就是说，它没有在植物的结构部件之间进一步重新分配。量¹³⁷进入空中部分的Cs约占工厂总存储量的2.5％。在实验（7天）中，在同化器官中累积的37.4–53.8％的放射性核素被带根分泌物运入纯溶液，而运入溶液中的放射性铯的储存量超过了根。尚未记录到根系表面水膜中¹³⁷ Cs的运动。
