Biological effects of radionuclides on plants
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.
