Abstract

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.

放射性核素对植物的生物学效应。
在分析文献和个人资料的基础上,确定了剂量学原理,并分析了放射性核素在空中和根部给药时对植物的生物效应。用标准LD50和UD50比较了大麦的辐射敏感性及其与辐照时植株生长阶段的关系。考虑了利用生物信息的相关参数,如评价小剂量辐射引起的生物效应的敏感性指标的可能性。根据所获得的数据的相关性,对不同发育时期受放射性核素影响的谷物收成损失的可能性作出了预测。
