“…The Monte Carlo method, which is used to establish transport codes, has proved to be efficient for simulating different types of irradiation for objects of various shapes and geometries [4,[52][53][54][55]. Table 3 provides transport codes for simulating the interaction of particles with the matter as well as energy ranges and materials that can be used in simulation [56].…”

“…While the EGSnrc and PENELOPE codes are limited in their application to the objects of simple geometry [5,6], transport codes MCNPX and GEANT4 are more widely used in the industry as these are more comprehensive instruments for simulating a wider variety of physical processes representing the interactions of electrons, photons, protons, and neutrons [7,8]. The MCNPX code is used in nuclear medicine, radiation safety, accelerator development, and modeling industrial irradiation of biological objects and materials [52]. GEANT4 is currently the most complete set of tools for simulating the passage of particles through matter [8].…”

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.
