“…In this way, it is more cost-effective and environmentally friendly than traditional alternatives, requiring less energy and generating less waste. 70 There are different sources of ionizing radiation used in different sectors of industry and agriculture: 71,72 γ-radiation, that is constituted by photons produced from radioactive isotopes cobalt-60 ( 60 Co) and cesium-137 ( 137 Cs), and accelerators, capable of producing electron beams and X-rays. Radioisotopes are useful due to their permanent source, high efficiency associated with their penetrating power and their easy replacement.…”

Due to the growing demand in society for healthier foods, scientific communities are searching and developing new ingredients. In this context, agro-industrial residues, which can have a negative impact on the environment, represent a natural source for bioactive compounds and their recovery can contribute to economic and environmental sustainability. Ionizing radiation is a clean and eco-friendly technology that can be used to improve the extraction of bioactive compounds. The aim of this review, after presenting general aspects about bioactive compounds in agro-industrial residues and radiation technologies, is to focus on the effects of ionizing radiation on the extraction of bioactive compounds from these residues and related bioactive properties. Irradiated residues were demonstrated to have enhanced bioactive characteristics that turn the prepared extracts suitable for applications in food industry, resulting in high-added-value products as well as reducing adverse impacts on the environment.

“…Food safety is a major concern these days with the increase in a number of consumers across the world and frequent cases of food poisoning as a result of improper handling of products. The modern trend of convenience food calls for treatment methods that would ensure human health and environmental safety while extending the shelf life of processed and prepackaged foods [1][2][3].…”

“…While the doses specified in the international regulations cover all types of foodstuffs, some adjustments are required for certain categories of products to achieve the desired result. The acceptable dose range varies from product to product [1][2][3][4][5][6][7]. It is just as important not to go below the lower limit as not to exceed the upper limit.…”

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.
