The investigation had the aim to evaluate the effects of low doses (< 1-10 cGy) of ionizing radiation on the physical-chemical qualities of high-purification water. It had also the goal to study germination rate and energy and sprouting of four species of higher plants exposed directly and indirectly (watering) to alpha- and beta-radiation from radionuclids sources. When compared with intact water, after exposure to beta-particles electrical currents in water-filled containers consistently tended upward and downward after exposure to alpha-particles. Radiation-induced changes in water parameters were observed throughout the experiment with higher plant seeds. Evaluation of the effect of irradiated water on sprouting showed that plant sensitivity varied with species and depended on type of radiation particles. Neither alpha- nor beta particles affected the wheat sprouts; however, both types of particles inhibited growth of mustard and accelerated growth of lentil and haricot Mash as compared with control crops. The investigation suggests that plant species for space greenhouses should be selected with account of their radioresistance and radiosensitivity.
该研究旨在评估低剂量（<1 - 10 厘戈瑞）电离辐射对高纯水物理化学性质的影响。其目标还包括研究四种高等植物直接和间接（通过浇水）暴露于放射性核素源的α和β辐射后的发芽率、活力及发芽情况。与未受辐射的水相比，暴露于β粒子后，充满水的容器中的电流在暴露于α粒子后持续上升和下降。在整个高等植物种子实验过程中都观察到了辐射引起的水参数变化。对辐照水对发芽影响的评估表明，植物的敏感性因物种而异，并取决于辐射粒子的类型。α粒子和β粒子都未影响小麦发芽；然而，与对照作物相比，这两种粒子都抑制了芥菜的生长，加速了小扁豆和菜豆的生长。该研究表明，太空温室的植物物种应根据其抗辐射性和辐射敏感性来选择。
