On the basis of analysis of the literature and personal data, principles of dosimetry were determined and an analysis was given of biological effects of radionuclides on plants when administered aerially and by root. A comparison was made of radiosensitivity of barley and dependence of sensitivity on the growth phase of the plant at the time of irradiation with a standard LD50 and UD50. The possibility of using correlated paramaters of bioinformation, such as the sensitivity indicator of evaluation of biological effects caused by small radiation doses, is considered. On the basis of correlations of the data obtained a prognosis is made of the probability of losses in harvest of grains subjected to radionuclides at various periods of development.
在对文献和个人数据进行分析的基础上，确定了剂量测定原则，并对放射性核素通过空气和根部施用于植物时对植物的生物学效应进行了分析。比较了大麦的放射敏感性以及在以标准LD50和UD50进行辐照时敏感性对植物生长阶段的依赖性。考虑了使用生物信息相关参数的可能性，例如评估小辐射剂量引起的生物学效应的敏感性指标。根据所获得数据的相关性，对处于不同发育时期受到放射性核素影响的谷物收获损失概率进行了预测。
