“…For each type of product, it is necessary to select the range of radiation doses [5][6][7][8], the radiation dose rate [9], the irradiation method, which includes the choice of the source of ionizing radiation and its operation mode [10], the relative position of the source and the processed object, and the container for placement-processed products, packaging, etc. [4,[11][12][13]. Noncompliance with the technological regimes of irradiation leads to chemical changes in the product, and, as a result, to a change in its organoleptic, nutritional, and structural properties.…”

One of the most important tasks in the food industry is the search for alternative biochemical markers of radiation treatment in dietary, chilled meat products such as chicken and turkey. Major organic volatile chemicals found in meat products can be precisely identified using gas chromatography coupled with mass spectrometry. In the response to the needs of the food industry, our research team conducted a series of experiments involving the irradiation of chilled poultry meat using an electron accelerator. The experiments showed that the concentration of pure volatile organic compounds in saline solution dropped exponentially with an increase in the irradiation dose, which proves that these chemicals decomposed when exposed to ionizing radiation. However, when turkey meat was exposed to an electron beam with doses up to 1 kGy, the concentration of alcohols, aldehydes, and ketones peaked, only to decrease with an increase in the irradiation dose up to 2 kGy, and then went up slightly when the irradiation dose was within the range from 2 kGy to 10 kGy. To determine the reason behind the nonlinear dependencies of organic compound concentrations in turkey meat on the irradiation dose, we developed a mathematical model that acknowledges the presence of two opposing processes, those of decomposition and accumulation of organic compounds as a result of the decomposition of other compounds that can be found in turkey meat.

The research explores a wide range of applications for electron accelerators in industrial irradiation processing. It also compares the physical properties of electron beams, dose ranges, and methods used for irradiation of polymers, medical items, transplantology objects, pharmaceuticals, and foods. Moreover, the study discusses the depth dose non-uniformity in objects irradiated with accelerated electrons. The research also highlights the dependency of geometry, density, and chemical composition of the object on the dose distribution. Another focus of the study is computer simulation of electron irradiation method, encompassing all physical and technical parameters to assess the dose distribution throughout the irradiated objects, since without knowing the precise electron beam spectrum, it is impossible to accurately reconstruct the dose distribution throughout the objects. Considering that the beam spectrum cannot always be identified, especially for industrial accelerators, the study presents algorithm for reconstructing the dose distribution in irradiated objects. The final part of the research provides methods for increasing the dose uniformity throughout objects irradiated with electron beams.

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.
