“…The experiment was repeated three times for both types of seeds for all doses. The dose absorbed by the samples was estimated using the algorithm described in [15], taking into account the time of exposure, beam current, and charge absorbed by the plate during each irradiation session, seen in table 1. Flax seeds were irradiated with the doses of 0, 5, 10, 30, 50 and 100 Gy, wheat seeds were treated with the doses of 0, 5, 10, 20, 30, 40, 50, 100, 200 and 300 Gy.…”

Radiation technologies are widely used in agriculture to accelerate the sprouting of plants, increase crop yields, improve product quality, and destroy pathogenic microflora. This article assesses the effect of treatment with accelerated electrons in various doses on the germination of wheat and flax seeds, as well as on their phytosanitary state. It was established that the most efficient dose for flax variety Severny is 10 Gy, since this dose not only showed the most considerable increase in the germination rate by 38% but also decreased the number of fungi in seeds by 15 % and reduced the average diameter of the remaining colonies by 30% or more. For spring wheat variety Novosibirskaya 29, however, the doses which would be able to significantly reduce the number and the diameter of colonies without causing the inhibition of seed germination were not found.

This study focuses on achieving a higher uniformity of 10 MeV electron treatment of cylindrical products by including aluminum modifiers of different thicknesses in the irradiation scheme. It was simulated the irradiation of cylindrical water phantom by beams of accelerated electrons with an energy of 10 MeV from two opposite sides using GEANT 4. During the simulation, aluminum plates-modifiers of different thicknesses of 1, 1.5 and 2 mm were added between the cylindrical phantom and the beam output in order to assess dose uniformity inside the phantom. It was found that the higher the thickness of aluminum plates, the more uniformity could be achieved. While 1 mm and 1.5 mm plates enable the efficiency ratio of 30 % and 45 %, respectively, a 2 mm modifier increases the uniformity of irradiation up to 60 %. In this way, computer modeling proves that inserting beam plates-modifiers between irradiated samples and beam output for irradiation from two opposite sides allows to considerably increase the uniformity of sample irradiation with complex geometry.

“…The doses absorbed by potato tubers were determined using computer simulation with the program code GEANT 4, based on the Monte Carlo method. The simulation was carried out taking into account the geometry of the samples and the technical characteristics of the accelerator, such as the spectrum of electrons obtained from it, in line with the method described in [18].…”

The study perpersents the influence of electron irradiation on on the phenology and productivity of potatoes inhabited by the fungus Rhizoctonia solani Kuhn. Potato samples were irradiated with the doses ranging from 0.02 kGy to 3.0 kGy. It was found that the pre-planting irradiation of seed potato tubers with the doses of 0.02-0.15 kGy led to a delay in plant development, and irradiation of tubers with over 0.2 kGy resulted in the death of plants. The maximum number of large tubers was obtained from samples irradiated with the dose of 0.15 kGy. The yield of potato tuber samples irradiated with the dose of 0.02 kGy corresponded to that of the control samples. Irradiation of potato seed tubers with a dose of 0.04 kGy led to a significant decrease in the colonization of the surface of tubers of the new crop with Rhizoctonia solani, while irradiation of potato tubers with a dose of 0.15 kGy completely eliminated the pathogen.
